In R-patched_2003-10-20, subsetted 1-D arrays no longer get converted to vectors. The NEWS file documents this change, as an indirect result of bug report 4110. I just wanted to mention this can break code in some rather obscure ways, such as this toy example:
R> x <- sort(tapply(1:8, rep(1:4,2), sum)) # Was vector, now is 1D array R> y <- matrix(1:4, 1,4) # 1x4 matrix R> x + y # Used to return a 1x4 matrix Error in x + y : non-conformable arrays I agree with the change, but I would beware that some puzzled users may not associate new "tapply problems" with this news item. Also, *should* you be able to add a (4) array to a (1,4) array? -- -- David Brahm ([EMAIL PROTECTED]) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
