[R] package forecast is not working properly

[David Winsemius]

This has been reported once on rhelp and once on StackOverflow and both times the advice to update to R 3.2.1 was effective in removing the difficulty. (You did get a warning.)

R 3.2.1 changed the number of arguments to nchar and this was announced in the NEWS.
