R - generate a vector with names of months (like LETTERS)

> format(ISOdatetime(2000,1:12,1,0,0,0),"%b")

gives:

 [1] "Jan" "Feb" "Mrz" "Apr" "Mai" "Jun" "Jul" "Aug" "Sep" "Okt" "Nov" "Dez"

where the month names depend on local settings. If you use %B instead of %b you get the non abbreviated months. How ever, there is also an easier way if you want the months in English: the vector

> month.name
 

gives

 [1] "January"   "February"  "March"     "April"     "May"       "June"     
 [7] "July"      "August"    "September" "October"   "November"  "December" 

or

> month.abb
 

gives

 [1] "Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct" "Nov" "Dec"
