I'm trying to include some notes on LaTeX preamble requirements that will be needed to make certain options available in a package. I need to get the following to render correctly in the .Rd file, but I consistently get the error
Error: Failure in roxygen block beginning sprinkle.R:1 Mismatched braces:
The offending section of (roxygen tagged) code is below
#' \tabular{ll}{
#' Sprinkle \tab LaTeX Package(s) \cr
#' \code{font_color} \tab \code{\\usepackage[dvipsnames]\{xcolor\}} \cr
#' \code{bg, bg_pattern} \tab \code{\\usepackage[dvipsnames,table]\{xcolor\}} \cr
#' \code{border_style} \tab \code{\\usepackage\{amssymb\}} \cr
#' \\ \\ (with vertical dashed lines) \tab \\usepackage\{graphicx\} \cr
#' \\ \\ \tab \code{\\makeatletter} \cr
#' \\ \\ \tab \code{\\newcommand*\vdashline\{\\rotatebox[origin=c]\{90\}\{\$\\dabar@\\dabar@\\dabar@\$\}\}} \cr
#' }
As soon as I take out the @ symbols, it works fine. How does one go about writing @ in R help files?
