overwriteDir() overwrite = "overwrite" argument not working if directory does not exist (?)

[banfai]

Quitting from lines 649-662 (report_dge_gse.Rmd) 
Error in createDir(dir) : 
  Directory access not possible: results/edgeR_output
Calls: <Anonymous> ... eval -> eval -> slurmEdgeR -> <Anonymous> -> createDir

Execution halted

If I create results/edgeR_output then it doesn't throw an error.

I suspect it goes wrong here:

ribiosUtils/R/file_dir.R

Line 183 in 3e0de3c

action=c("ask", "overwrite", "append", "no")) {

but the error message is coming from this function:

ribiosUtils/R/file_dir.R

Line 69 in 3e0de3c

createDir <- function(dir,showWarnings=FALSE, recursive=FALSE, mode="0777") {

At the moment this does not make sense for me, by reading the code it should not fail at that position.
