I had the same problem, it was the locale.

Using Sys.setlocale(category = "LC_TIME", locale = "pt_BR") before the function solved it for me.

I had the same problem, it was the locale.

Using:

Sys.setlocale("LC_TIME", "Portuguese") # Windows

before the function

this solved it for me.

for more: ?Sys.getlocale()

Examples

Sys.getlocale()
Sys.getlocale("LC_TIME")

Not run:
Sys.setlocale("LC_TIME", "de") # Solaris: details are OS-dependent
Sys.setlocale("LC_TIME", "de_DE.utf8") # Modern Linux etc.
Sys.setlocale("LC_TIME", "de_DE.UTF-8") # ditto
Sys.setlocale("LC_TIME", "de_DE") # OS X, in UTF-8
Sys.setlocale("LC_TIME", "German") # Windows

End(Not run)

Sys.getlocale("LC_PAPER") # may or may not be set

Not run:
Sys.setlocale("LC_COLLATE", "C") # turn off locale-specific sorting,
usually, but not on all platforms
