If a function contains the pattern `<-` it is (with a few exceptions) deemed to be a replacement function and in particular must have second argument `value` to pass R CMD check.
Consider the function %<->% or any other function containing <- within grapes. I claim that such functions should not be considered replacement functions and thus the R CMD check should not require its second argument to be `value`. Recommend in the function tools::checkReplaceFuns grep("<-", objects_in_code, value = TRUE) be changed to grep("<-$", objects_in_code, value = TRUE) Hugh. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
