Dear all, I had the same problem when I submitted my R package 'metan' to CRAN for the first time.
"Please ensure that your functions do not write by default or in your examples/vignettes/tests in the user's home filespace (including the package directory and getwd()). In your examples/vignettes/tests you can write to tempdir()" I have several 'summary()' functions like: *summary.waasb <- function(object, export = FALSE, file.name <http://file.name> = "summary_waasb", ...) { # do all I need here if (export == TRUE) { sink(paste0(file.name <http://file.name>, ".txt")) # do all I need here sink() }}* All 'export' arguments are set to 'FALSE'. So, no file is generated in the user's working directory. Is the above function not according to the CRAN policies? In two vignettes I have a code like: *```{r, eval=FALSE }summary(stat_ge, export = TRUE)```* Please, note that 'eval = FALSE'. Could this be the problem? The suggestion is to write to a tempdir() but even looking at the Duncan Murdoch's answer I cannot see how to do that in my case. Looking for any suggestion.

Save the file to the temporary directory, ẹ.g. filename <- file.path(tempdir(), "Prodục.csv") write.csv(something, file = filename) You could clean up at the end of the example with unlink(filename) but you shouldn't rely on this alone to prevent the error: if you're writing files, you should *only* be doing it in the temporary directory.
