 You could construct a vector of the first of the month for some year
and then use months() or format() on it:

 > months(ISOdatetime(1960,1:12,1,0,0,0))
  [1] "January"   "February"  "March"     "April"     "May"       "June"
  [7] "July"      "August"    "September" "October"   "November"  "December"

 > format(ISOdatetime(1960,1:12,1,0,0,0),"%b")
  [1] "Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct" "Nov" "Dec"

 Note these are locale-dependent, so les Francais will see something
else. Probably "Jan","Fev","Mar","Avr" and so on...
