Hello list,
I was hoping I could get some help on something which is really giving
me a headache. I am using R version 2.14.1 (2011-12-22)
(Platform: x86_64-pc-mingw32/x64 (64-bit))
An object which is supposed to have times has a few elements listed as
not times but NA's
> ls()
[1] "todelete"
> class(todelete)
[1] "POSIXlt" "POSIXt"
> todelete
[1] "2011-03-27 00:59:57" "2011-03-27 00:59:58" "2011-03-27 01:00:01"
"2011-03-27 01:00:02"
> is.na(todelete)
[1] FALSE FALSE TRUE TRUE
> as.numeric(todelete)
[1] 1301187597 1301187598 NA NA
but on another machine, from a colleague, over the same workspace,
returns this, as expected:
> ls()
[1] "todelete"
> class(todelete)
[1] "POSIXlt" "POSIXt"
> todelete
[1] "2011-03-27 00:59:57" "2011-03-27 00:59:58" "2011-03-27 01:00:01"
[4] "2011-03-27 01:00:02"
> is.na(todelete)
[1] FALSE FALSE FALSE FALSE
> as.numeric(todelete)
[1] 1301180397 1301180398 1301180401 1301180402
any suggestions about what might be going on here would be greatly
appreciated.
all the best
Tiago
