Dear Yihui and cderv,

I recently encountered the following error message when I tried to knit my old rmd file, which worked perfectly two months ago. The mistake will disappear if I switch the latex engine from pdflatex to xelatex or lualatex. However, for the last two engines, all my latex customizations do not work. I tried everything mentioned on this page.

! Undefined control sequence.
l.71 \NewDocumentCommand
\citeproctext{}{}

Here is my original yaml code

title: "xx"
author: xx
abstract:
#|

```{=latex}

xx.

```

date: "r Sys.Date()"
fontsize: 11pt
output:
bookdown::pdf_document2
header-includes:

\usepackage{textcomp}
\usepackage{utopia}
\usepackage{lineno}
\linenumbers
\usepackage{float}
\floatplacement{figure}{H}
\usepackage{caption}
\captionsetup[figure]{font=scriptsize}
\captionsetup[table]{font=scriptsize}
linestretch: 1.5
link-citations: yes
linkcolor: blue
bibliography: bibliography.bib
csl: apa.csl

Thank you in advance!

You did not format the Rmd content correctly, so hard to know if you set it correctly.

This error mentions NewDocumentCommand does not seem to be defined. So I would check your latex version to be sure you are using a recent that has this command. It should be inside LaTeX and not in a package.

This is used by pandoc to create a citeproctext command when CSL is used with Pandoc's citeproc.

Raylc 2024-05-13 14:20:51

Christophe thanks for your reply! I just uninstalled my TeXLive and installed MikTeX, and it works perfectly this time. This yaml code chunk worked pretty well several weeks ago, but it stopped working since I updated RStudio, making me suspect that it is the fault of RStudio update.

I get following error after my code have usually been working:
! LaTeX Error: File `tabu.sty' not found.

! Emergency stop.
<read *>
I have done everything listed above with no luck

cderv 2024-05-22 16:00:39

! LaTeX Error: File `tabu.sty' not found.

You are just missing the tabu CTAN package; If you install it, this should work. We can't say why it was not installed automatically. It shoud if you are using TinyTeX and tinytex R package with R Markdown.

I have done everything listed above with no luck

You can also search online for such error. Those are not TinyTeX specific. They are LaTeX errors. You should be able to find help online easily

Hi Yihui and cderv,
Thanks for all your work on this package, really appreciate your hard work. I am trying to use this package in an aws lambda. When I knit with the rmarkdown::render function, I get:

! I can't write on file FileName.log
(Press Enter to retry, or Control-D to exit; default file extension is `.log')
Please type another transcript file nameERROR [2024-05-24 04:45:54] LaTeX failed to compile /tmp/Daily_Roster_Pitching_Log_and_Payroll_2024-05-24.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips.

Thank you in advance

cderv 2024-05-24 08:15:07

You need write access for the LaTeX compilation to work. It seems everything happens in /tmp but maybe some environment are configured for Log file to be written elsewhere. This seems environment specific, and I don't know about aws lambda. Sorry

mbrandt00 2024-05-24 15:40:33

Thanks for the reply. Knitting to an HTML file worked inside the lambda environment, so it must be a problem with lambda accessing the necessary pdflatex binaries.

cderv 2024-05-24 21:30:07

TeX Live and LaTeX could do some processing in different places, also if lambda tweaked some options. R Markdown does not control much the LaTeX processing, but usually it applies in same place as the Rmd to Latex conversion. So not sure where to look

skinsella 2024-07-03 12:10:38

Hi thanks for all your work on this package. I am compiling and it won't work for some reason, error is

! Undefined control sequence.
@{} >{\raggedright \arraybackslash
}p{(\columnwidth - 6\tabcolsep...
l.866 ...width - 6\tabcolsep) * \real{0.1944}}@{}}

When I go to l.866, there does not seem to be anything wrong.

cderv 2024-07-03 12:50:36

Without any example of what you tried to render this is very hard to help.

This is a LaTeX issue meaning somehow the .tex file contains some error. You need to look into it, or in what is creating this code in the .Rmd or .qmd file.

Possibly, this is missing a CTAN package which brings a command you don't have.

So this all depend on

Which content is creating this command ?
What is creating the tex file ?
And more.

There is no context to your question so this is really some guesses from us...

skinsella 2024-07-03 15:33:31

Sorry!

I'm using this .tex file: https://github.com/svmiller/svm-r-markdown-templates/blob/master/svm-latex-cv.tex

skinsella 2024-07-04 06:26:55

Hi, I've figured this out thanks to your prompt to go look at the .tex file. It was deprecated. I redid the yaml based on the author's updated .tex and we're off. Thanks!

sally982 2024-08-05 11:36:06

this is my r shiny's application :

library(shiny)
library(DT)
library(rmarkdown)
library(dplyr)

Données d'exemple

data <- data.frame(
Nom = c("Alice", "Bob", "Charlie", "David"),
Age = c(24, 30, 35, 40),
Ville = c("Paris", "Lyon", "Marseille", "Nice")
)

UI

ui <- fluidPage(
titlePanel("Télécharger un tableau filtré en PDF"),

sidebarLayout(
sidebarPanel(
selectInput("ville", "Sélectionnez une ville :", choices = unique(data$Ville), selected = unique(data$Ville)[1]),
sliderInput("age", "Sélectionnez un âge :", min = min(data$Age), max = max(data$Age), value = c(min(data$Age), max(data$Age))),
downloadButton("download_pdf", "Télécharger PDF")
),

mainPanel(
  DTOutput("table")
)

)
)

Server

server <- function(input, output) {

Filtrer les données en fonction de la ville et de l'âge sélectionnés

filtered_data <- reactive({
data %>% filter(Ville == input$ville, Age >= input$age[1], Age <= input$age[2])
})

Rendu du tableau interactif

output$table <- renderDT({
datatable(filtered_data())
})

Télécharger le PDF

output$download_pdf <- downloadHandler(
filename = function() {
paste("rapport-filtre-", Sys.Date(), ".pdf", sep = "")
},
content = function(file) {
# Rendre le rapport RMarkdown en PDF avec toutes les villes filtrées par l'âge
params <- list(data = data, age = input$age)
rmarkdown::render("C:/Users/s.rhazi/Downloads/report.Rmd", output_file = file, params = params, envir = new.env(parent = globalenv()))
}
)
}

Lancer l'application

shinyApp(ui = ui, server = server)

and this is the r markdown part :

title: "Rapport de données filtrées"
output:
pdf_document:
keep_tex: true
header-includes:

\usepackage{booktabs}
params:
data: NULL
age: NULL

knitr::opts_chunk$set(echo = FALSE, warning = FALSE, message = FALSE, results = 'asis')

library(dplyr)
library(knitr)
library(kableExtra)

# Filtrer les données selon l'âge
filtered_data <- params$data %>% filter(Age >= params$age[1], Age <= params$age[2])

# Générer les tableaux pour chaque ville
for(ville in unique(filtered_data$Ville)) {
  ville_data <- filtered_data %>% filter(Ville == ville)
 
  if(nrow(ville_data) > 0) {
    cat("\\section*{", ville, "}\n\n")
   
    # Générer le tableau sans détails supplémentaires
    ville_data %>%
      kable("latex", caption = "Tableau des données") %>%
      kable_styling(position = "center", full_width = FALSE) %>%
      row_spec(0, bold = TRUE, background = "gray") %>%
      row_spec(1:nrow(ville_data), background = "lightgray") %>%
      print()
   
    cat("\n\n")
  } else {
    cat("\\section*{", ville, "}\n\n")
    cat("Aucune donnée disponible pour cette ville.\n\n")
  }
}

and they keep giving me errors , I installed MIKTEX and I did all of this

CRAN version

install.packages('tinytex')
tlmgr_install()

or the development version on GitHub

remotes::install_github('rstudio/tinytex')

tinytex::parse_packages()

latexmk(engine = 'pdflatex', emulation = TRUE)

update.packages(ask = FALSE, checkBuilt = TRUE)
tinytex::tlmgr_update()

options(tinytex.verbose = TRUE)

update.packages(ask = FALSE, checkBuilt = TRUE)
tinytex::tlmgr_update()

tinytex::tlmgr_install(c('texlive-scripts', 'dehyph-exptl'))
tinytex::tlmgr_install(c('texlive-scripts', 'dehyph-exptl'))

tinytex::uninstall_tinytex()
tinytex::install_tinytex(dir = "C:/TinyTeX")

TinyTeX (tinytex::reinstall_tinytex())

and this is the error : Listening on http://127.0.0.1:3130

In R Markdown I had the following errors when I try knitting using the papaja apa 6th edition format:

tlmgr: Remote database (revision 73229 of the texlive-scripts package) seems to be older than the local installation (rev 73240 of texlive-scripts); please use a different mirror and/or wait a day or two. ! LaTeX Error: File caption.sty' not found. ! Emergency stop. <read *> Error: LaTeX failed to compile Untitled.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Untitled.log for more info.

In addition: Warning message: In system2("tlmgr", args, ...) : running command ''tlmgr' search --file --global '/caption.sty'' had status 1 Execution halted

I have tried everything and nothing changes or a new error will appear…

Im using the R version 4.4.2 for Mac.

cderv 2024-12-31 14:00:24

Probably something related to your TeX Live installation, or just your network. It seems it couldn't reach the CTAN server to install the missing caption.sty.

So check your network and your TinyTeX (or TeX Live) install - you could try reinstalling.

Hi all, I'm getting the above error when trying to knit in Rstudio. I've reinstalled TinyTex. It seems to be an issue with TeX.

I went to line 99 in the .tex file. here it is:

\setcounter{secnumdepth}{-\maxdimen} % remove section numbering
\usepackage[amsmath]
\ifLuaTeX
  \usepackage{selnolig}  % disable illegal ligatures
\fi
\usepackage{bookmark} #LINE 99 
\IfFileExists{xurl.sty}{\usepackage{xurl}}{} % add URL line breaks if available
\urlstyle{same}
\hypersetup{

Where does this HTML come from? Copy and paste from RStudio IDE copy, or do you see that in your file or in the console/terminal?

Unfortunately, we can't say much about this issue; this depends on your document's content.

ecceeecs 2025-04-09 04:51:25

Hi, it comes from "Render" in RStudio (line is now 109 since I added some stuff).

cderv 2025-04-09 09:06:30

Something in your document is leading to faulty .tex file. Look at the .log file and try to find the Rmd part that can cause this.

Without idea about the content of the .Rmd that can cause this, we can't unfortunately help further

Dear Yihui,

I'm trying to combine a Plotly plot and user text responses into a PDF report generated from an RMarkdown file in a Shiny app.

The downloadHandler part for "Download Plot (PNG)" works and I get a nice png plot but "Download PDF Report" doesn't work in which I tried to combine the user responses with the Plotly plot.

It gives error:
Warning: Error in : LaTeX failed to compile What I have tried: followed steps here: https://yihui.org/tinytex/r/#debugging.

I have installed Tinytex and updated it using

tinytex::tlmgr_update().

I made sure all packages are upto date

update.packages(ask = FALSE, checkBuilt = TRUE)

library(shiny)
library(plotly)

writeLines(
  con = file.path(tempdir(), 'report_template.rmd'),
  text =

output: pdf_document
params:
  responses: !r list()
  plot_path: ""
---

```{r, include=FALSE}
options(tinytex.verbose = TRUE)
```


```{r}
for (i in seq_along(params$responses)) {
  cat(sprintf("**Response %d:**\n", i))
  cat(params$responses[[i]], "\n\n")
}
```

' )

Please format your post correctly regarding code block syntax.

Also does your parametrized rmarkdown::render() with your plotly graph works outside of shiny app ?

Thanks. I edited the post. Yes, the parameterized rmarkdown::render() with plotly graph works outside of the shiny app.

Then it is probably related to how shiny will run the code you pass into downloadHandler()

I would suggest try to debug the shiny app and look at the log file from TeX compilation. This will tell you what the compilation error is.

Without knowing why LaTeX is failling in shiny context, it will be hard to help debug.

Okay. I found the log file from TeX compilation.
texput.log

You got *** (job aborted, file error in nonstop mode)

It does not tell much - except that it fails completely. You need to understand what is different in your shiny app context for the rendering.

Check all resources are available to the .Rmd when in temp directory maybe.

It does not seem like a TinyTeX problem, but more like an environment problem when you are rendering in Shiny context
