r-markdown

This is a related question to a post I made a few weeks ago here . I am trying to embed QR codes in a new column in a list of dataframes. The QR code will contain the numerical result from the other column and can be scanned into our lab information system. Thus far i am able to generate a dataframe with a column containing QR codes using RMarkdown, but I can't seem to do it when I try to adapt this code to a list of dataframes. Here is an example of what does what I want with a single dataframe: --- title: "QR Code in Column" author: "dorton" date: "2019/01/20" output: pdf_document --- ```{r

I'm using RStudio Version 0.99.896 and trying to compile an article which uses RJournal template (.Rmd). The thing is, whenever I try to compile a simple chunk like ```{r} l = list(a = list(b = c(1,2)), b = c(3,4)) l$a l[[1]]$b ``` i get this awful output (in the .pdf): \begin{Schunk} \begin{Sinput} l = list(a = list(b = c(1,2)), b = c(3,4)) l$a \end{Sinput} \be- gin{Soutput} #> b > [ 1 ] 12 \textbackslash{}end\{Sinput\} \begin{Soutput} > [1] 1 2 \end{Soutput} \textbackslash{}end\{Schunk\} \textbackslash{}begin\{Schunk\} \begin{Sinput} I don't even have to use the problematic $ (dollar sign)

I'm trying to get a watermark image like here: How to add a watermark image on rmarkdown? I almost did it, but as I wrote on my original question the background.png image that the \includegraphics get comes from C:\Program Files (x86)\MiKTeX 2.9\tex\plain\present I'm currently using my Latex code from an external file using the follwing at beginning of my .Rmd: output: pdf_document: includes: in_header: header.tex And in header.tex I'm using the following code: \usepackage{eso-pic,graphicx,transparent} \AddToShipoutPictureFG{ \put(0,0){% \parbox[b][\paperheight]{\paperwidth}{% \centering {

What does Work I am able to make the subtitle of my pdf file dynamic based on user input. I am also able to generate a 'semi-dynamic' file name using the subtitle field from the YAML (the working code is given below) What doesn't Work However I am not able to do both, being a subtitle and output file which are based upon the users input. As rmarkdown::yaml_front_matter(inputFile)$title does work I tried to use rmarkdown::yaml_front_matter(inputFile)$subtitle however it seems to have the unevaluated r-code. A long shot was rmarkdown::yaml_front_matter(inputFile)$params$sub_title but that

I cannot show object in markdown document that are objects generated in different R script(within the same session). I would like to point out that I am newbie to markdown. So the code is as follows(''' are added before and after): {r eval=TRUE, echo=FALSE} head(output_by_size,10) # 1st line summary(cars) # 2nd line dim(iris) # 3rd line when I comment line 2nd and 3rd the following error is generated: Error in head(output_by_size, 10) : object 'output_by_size' not found Calls: ... withCallingHandlers -> withVisible -> eval -> eval -> head When 1st line is commented, lines 2nd and 3rd work as

Instead of Chapter X when creating a PDF from bookdown, I would like it to be "Módulo X" (in Spanish). So I would like to know how to change chapter name using bookdown. My YAML is: --- title: "TITLE" author: "Mario Modesto-Mata" date: "`r Sys.Date()`" output: pdf_document description: This is a minimal example of using the bookdown package to write a book. The output format for this example is bookdown::gitbook. documentclass: book link-citations: yes bibliography: book.bib site: bookdown::bookdown_site language: label: chapter_name: "Módulo" --- I tried with the last three line codes, with
