Hello,
You can use the built in variable month.name to get the calendar order
and match it with your file names.
i <- match(sub("\\.PDF", "", file.names), month.name)
file.names[i]
#[1] "January.PDF" "February.PDF" "March.PDF"
Hope this helps,

Hi All--
I used base R list.file function to read files from a directory. The
file names are months (April, August, etc). That's the system reads
them in alphabetical order., but i want to reordered them in calendar
order (January, February, ...December).. I thought i might be able to
do it via RegEx or possibly gtools package, I am wondering if there is
an easier way.
Thanks--EK
Example
path = "C:/Users/name/Downloads/MyFiles"
file.names <- dir(path, pattern =".PDF")
Example output
Output:
"February.PDF" "January.PDF" "March.PDF"
Desired output
"January.PDF" "February.PDF" "March.PDF"
