CRAN package timeDate

[Kurt Hornik]

Guys,

This actually fails R CMD check in most cases, see

  http://cran.r-project.org/web/checks/check_results_timeDate.html

from

timeDate/R/subset.R:            length(grep("[a-Z]", subset)), sep = "")

which is invalid in many locales (not with a complete UTF-8 one, though,
but e.g. with LC_COLLATE=C).

If you want the locale's idea of letters, you can use [[:alpha:]]
instead.  If just the ASCII letters, you need to give them explicitly.

Can you pls have an update fixing this?

Best
