Dear CRAN: I am running 'R' on Linux as follows:
version
_ platform i686-redhat-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 2 minor 6.0 year 2007 month 10 day 03 svn rev 43063 language R version.string R version 2.6.0 (2007-10-03)
I have a question about the behavior of "range()" with missing dates.
With the previous version (2.4?) , the command:
range( as.Date( c( "2007-11-06", NA ) ), na.rm = TRUE )
yielded:
[1] "2007-11-06" "2007-11-06"
Now I get:
[1] NA NA
Is this a bug?
Yes, I see in the "What's New" page:
"The Math2 and Summary groups (round, signif, all, any, max, min, summ, prod, range) are now primitive."
Is the "primitive" characteristic supposed to behave as above with missing dates?
Thanks for any help that you can provide.
This is really a question for r-devel or r-bugs, I think, but not for the CRAN maintainers. I would think it is a bug. Perhaps simply file a bug report? Best - -k ------- End of forwarded message -------
