Issue with %in% in roxygen comment

[ebridge2]

Hi,

I have the following roxygen comment:

#' @param community.attribute the attribute of the graph vertices denoting the vertex communities. Should be that \code{community.attribute %in% names(vertex.attributes(g))}.

that throws the roxygen warning:

Warning: @param <file#linenumber>: mismatched braces or quotes

when I delete the %in% the warning goes away. Is this desired behavior?

You need to escape % because it's the Rd commenting character. Alternatively, if you use markdown formatting (and the development version), roxygen2 will escape for you:

#' @param community.attribute the attribute of the graph
#'   vertices denoting the vertex communities. Should be that 
#'   `community.attribute %in% names(vertex.attributes(g))`.
