How to escape % in roxygen literate programming?
- by Karsten W.
The default value of a parameter of my function contains a "%". This seems to be a problem for roxygen, it produces a lot of warnings and R CMD check fails when trying to build latex documentation.
How can I make this function (and its documentation) work? Using %% or \% instead of % does not help.
#' Test escape \% from in-source documentation (roxygen).
#'
#' What happens when parameters contain special latex characters?
#'
#' @param x unsuspicious parameter
#' @param format sprintf format string (default "\%5.0f")
#'
#' @return formatted string
#' @export

testroxy <- function(x, format = "%5.0f") {
sprintf(format,x)
}
