[R] Getting the last day of the month.

[Jeffrey J. Hallman]

The TimeIndex class in the 'fame' package handles this kind of stuff with ease.
> library(fame)
> ym <- 200212
> z <- lastDayOf(ti(100*ym + 1, tif = "monthly"))
> z
[1] 20021231
class: ti
> tifName(z)
[1] "daily"

a 'ti' object is a TimeIndex, and it has a tif (TimeIndexFrequency) embedded
in it.
