R as.Date function

Question

as often I have problems with the conversion of dates in R. Can anybody explain the following behavior to me?

as.Date('Dec-28-2003', '%b-%d-%Y') # returns NA
as.Date('Jan-04-2004', '%b-%d-%Y') # returns 2004-01-04

Yeah, I realized it's about the language setting. My R recognizes German dates only... (see answer below). Thanks for checking though! — quant_econ_geo, Oct 07 '18 at 15:34

Sorry, I got the answer. It's about the language setting, my R recognizes German dates only, i.e.

as.Date('Dez-28-2003', '%b-%d-%Y')

as in Dezember instead of December works fine. I used the lubricate package instead.

mdy('Dec-28-2003') # returns 2003-12-28
