变量名限制为256个字节

Question

roxygenize在以下代码上失败,并显示以下错误消息.关于该主题的其他帖子表明存在错位的字符.我找不到任何错误!你能发现这个问题吗？

#' My Title. My Description
#'
#' @return A n x n \code{\link{matrix}} where n = the number of variables.  Row and column names are in the same order and are equivalent to the variable names in \samp{timeSeriesData}.  Each entry [i,j] in the matrix is the covariance between variable i and variable j.
#' @callGraphPrimitives
#' @note some notes here
MyFunc = function( timeseriesData ,  method , decayFactor  )
{
}


Error in do.call(paste, c(trimmed.lines, sep = "\n")) :
  variable names are limited to 256 bytes

Edit1
如果我从长@return行中取出几个单词,上面的代码就可以了

Edit2
在roxygenize调用之前添加sessionInfo()结果.

这是一个众所周知的错误:请参阅此讨论,涉及Hadley Wickham,他是roxygen的贡献者.

工作轮是#' @return A n x n ...短线:你的线上有大约270个字符(包括三个句子),所以很容易分开.
