Re: [R] Problem with xtabs(), exclude=NULL, and counting NA's
Also see addNA. Works great. Sometimes R drives me crazy, but Hadley, you make it much easier for me That is nice. The addNA function does not exactly jump off the page for the (too) casual reader. In the context of the OP's original problem, these lines of code are illustrative: Here is an example from the actual dataset: xtabs(pwgtp~addNA(cut(pums.mex$JWMNP, c(0, 19, 65, Inf), include.lowest=TRUE))) addNA(cut(pums.mex$JWMNP, c(0, 19, 65, Inf), include.lowest = TRUE)) [0,19] (19,65] (65,Inf] NA 3905346787 252161914 xtabs(pwgtp~(cut(pums.mex$JWMNP, c(0, 19, 65, Inf), include.lowest=TRUE))) cut(pums.mex$JWMNP, c(0, 19, 65, Inf), include.lowest = TRUE) [0,19] (19,65] (65,Inf] 3905346787 2521 Thanks to all! __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Note that the variable below has been generated with cut(), if that matters.

Re: [R] Problem with xtabs(), exclude=NULL, and counting NA's
xtabs(~wkhp, x, exclude=NULL, na.action=na.pass) wkhp 20 30 40 45 60 NA 1 1 10 1 3 4 Thanks! I must say that this is slightly odd behavior to require both na.action= AND exclude=. Does anyone know of a justification? Shouldn't it be changed? vent Ah well, if R were internally consistent or corresponded to typical programming Unix practices, it just wouldn't feel the same ... /vent Cheers! -- David Winsemius, MD Heritage Laboratories West Hartford, CT __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
