I agree its overkill but prop.table generalizes to mulitple dimensions, in which case it becomes comparable to CrossTable, so I thought it was worth mentioning.
By the way, as the author of CrossTable, perhaps you might might consider generalizing CrossTable to the 1D case too? --- Date: Sun, 29 Feb 2004 19:19:29 -0600 From: Marc Schwartz <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]>,R-Help <[EMAIL PROTECTED]> Subject: RE: [R] Proportions again On Sun, 2004-02-29 at 18:27, Gabor Grothendieck wrote: > That's true; however, > > CrossTable(x,x) > > does give the desired counts and proportions in the margin > line at the bottom.

I had not considered that approach from a design perspective, but it does provide the requisite information. One could feasibly reduce some of the complexity of the table by setting some of the prop.* arguments to false: CrossTable(sex, sex, prop.c = FALSE, prop.t = FALSE) which would yield: Cell Contents |-----------------| | N | | N / Row Total | |-----------------| Total Observations in Table: 8 | sex sex | 1 | 2 | Row Total | -------------|-----------|-----------|-----------| 1 | 3 | 0 | 3 | | 1.000 | 0.000 | 0.375 | -------------|-----------|-----------|-----------| 2 | 0 | 5 | 5 | | 0.000 | 1.000 | 0.625 | -------------|-----------|-----------|-----------| Column Total | 3 | 5 | 8 | -------------|-----------|-----------|-----------| This gives you the proportions in the row margins versus the columns. You still end up with some extraneous data, but perhaps a little less so. Just seems like overkill to get the same information that: > prop.table(table(sex)) sex 1 2 0.375 0.625 gives you, without the lengthy function call. :-) Thanks Gabor.
