Goal Use a for loop to create sections with text, in-text results, and multiple figure references with associated figure captions in the figure list. The figure references/numbering should be seemless with figures numbered before and after these new sections. Note: The figures referenced in the for loop are generated earlier in

I'm trying to increment the section headers in my rMarkdown (PDF output) file by 1. Instead of # First resulting in 1 First , I'd like 2 First. I found a way to define the offset in html_output using the following syntax, but it doesn't work for pdf_output. --- title: "Untitled" author: "author" date: "date" output: html_document: toc: true pandoc_args: [ "--number-sections", "--number-offset=1" ] --- # First Header # First SubHeader This results in 2 First Header 2.1 First Subheader However, this syntax does not work for PDF documents: --- title: "Untitled" author: "author" date: "date"

I am working with R, knitr and pander, and I can't find the option that would allow me to print a grid on a table with pander. I tried : pander(tableToPrint, style='grid') but it doesn't do anything, neither with this option or with 'multiline', 'rmarkdown'... I always get an horizontal line, then the column names, another horizontal line, all my data and an horizontal line. I would like to have an horizontal line between every line. Another option would be to alternate row colors. scoa There is an old answer that gives the trick to do that in latex, but in needs a bit of adaptation to pandoc.

I have recently begun using knitr with Rstudio. I ran into the "No tex installation detected. Please install TeX before compiling." error in both my Ubuntu and windows OS's. After some research I was able to amend the issue in Ubuntu by adding the directory of my tex installation to PATH . I did this by including the following line in Renviron.site PATH=/usr/local/texlive/2013/bin:${PATH} However, the issue remains for my windows installation. I was unable to find the Renviron.site file, so I created one in the same directory of Renviron, and added the location of my tex installation in

I am using R notebook to preview the file. Even though all the code is in one chunk, a line gets separated into two. Would you please tell me how I can resolve this? As you can see all the code is in one chunk. However, when I run this chunk, it gets separated into two. I am not sure if it matters but here is the code I am running. library(MASS) par(mfrow=c(3,1)) hist(galaxies, breaks=500) hist(galaxies, breaks=100) hist(galaxies, breaks=50) Also here are the versions of R and RStudio. I an new to R so I am not sure what is causing this. If you need any other information, please let me know.
