[R] date conversion

[Joshua Wiley]

Hi Erin,

I am not sure what a "seq.Date object" is.  My first thought is that
you are talking about the date method for seq(), but there are
hundreds of packages I do not know.  In any case, here is what I think
you want.

## A small example is always nice
dat <- ts(1:12, frequency = 12,
  start = c(1998, 1), end = c(2010, 12))

## Achim and Gabor's wonderful package
require(zoo)
## now just convert to a date
as.Date(dat)
