RMarkdown: How to change the font color?

Question

In RMarkdown is there a way to specify the font color?

There doesn't seem to be an option while browsing through the chunk options

Answer 1

The answer given at the link provided by @Ben Bolker:

Roses are <span style="color:red">red</span>,  violets are <span style="color:blue">blue</span>. 

does work if you select HTML (ioslides) as the output format.

However, it does not work if you select pdf (beamer) as output format. If you want to create a pdf, use LaTeX syntax:

    Roses are \textcolor{red}{red}, violets are \textcolor{blue}{blue}. 

Answer 2

I create a function like this:

## Color Format colFmt <- function(x,color) {      outputFormat <- knitr::opts_knit$get("rmarkdown.pandoc.to")      if(outputFormat == 'latex') {     ret <- paste("\\textcolor{",color,"}{",x,"}",sep="")   } else if(outputFormat == 'html') {     ret <- paste("<font color='",color,"'>",x,"</font>",sep="")   } else {     ret <- x   }    return(ret) } 

Then you can use it inline like this:`r colFmt("MY RED TEXT",'red')`, and colored text will be rendered regardless of whether working on latex or HTML document.
