Thanks Yihui and Jeff. I've retrieved the default CSS file and made a tweak to it (changing a header 1 size just to test it) and saved it to the same local directory as my .Rmd file using the name 'mymarkdown.css' for testing.
I've added: options(rstudio.markdownToHTML = function(inputFile, outputFile) { require(markdown) markdownToHTML(inputFile, outputFile, stylesheet='mymarkdown.css') } ) to the top of my testfile.Rmd file so that my file now looks like: options(rstudio.markdownToHTML = function(inputFile, outputFile) { require(markdown) markdownToHTML(inputFile, outputFile, stylesheet='mymarkdown.css') } ) Title ======================================================== This is an R Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **Help** toolbar button for more details on using R Markdown). When you click the **Knit HTML** button a web page will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this: ```{r} summary(cars) ``` But when I knit it, it just writes the "options" chunk at the top of my document. Am I supposed to add something else to get the .rmd file to reference the css? I'm quite new to programming and R (as if you couldn't tell!), so not sure what additional steps I need to add. Thanks much. Jeff On Thu, Jan 30, 2014 at 1:48 PM, Yihui Xie <x...@yihui.name> wrote: > Exactly.
