That is the way, but you are not specifying the language (really locale) 
correctly.  See the R manuals, 
e.g.http://cran.r-project.org/doc/manuals/R-admin.html#Locales-under-Linux .

For me,
Sys.setlocale("LC_TIME", "es_ES.UTF-8")
appears to work.

There are international standards for this kind of thing: and then there 
is Windows ....
