R help - May 2006 - Function as.Date leading to error implying that strptime requires 3 arguments

I'm using R V 2.2.1.  When I try an example from the as.Date help page,
I get an error.
> x <- c("1jan1960", "2jan1960",
"31mar1960", "30jul1960")
> z <- as.Date(x, "%d%b%Y")
Error in strptime(x, format) : 2 arguments passed to 'strptime' which
requires 3
> 
Any suggestions would be appreciated.  

Thanks,

Rob

I can't reproduce this on my XP system:
> x <- c("1jan1960", "2jan1960",
"31mar1960", "30jul1960")
> z <- as.Date(x, "%d%b%Y")
> z
[1] "1960-01-01" "1960-01-02" "1960-03-31"
"1960-07-30"
> R.version.string # XP
[1] "R version 2.2.1, 2005-12-20"

I also tried it on 2.3.0 patched and could not reproduce it there
either.

Your system (unstated) is corrupted.  R runs its examples as part of it 
test suite, so this is not an error in R 2.2.1 (which is not current: see 
the posting guide which asked you to update *before* posting).  One 
possibility is that you have strptime from a much earlier version of R in 
use somehow.

I suggest you remove all versions of R from your system and reinstall one 
latest version (2.3.1 beta).
