[Rd] doc buglet / bug: row / col as.factor requires dimnames
col(matrix(0, 5, 5), as.factor=TRUE) fails> col(matrix(0, 5, 5), as.factor=TRUE)Error in factor(.Internal(col(dim(x))), labels = colnames(x)) : invalid labels; length 0 should be 1 or 5 when the matrix has no dimnames. This is not as advertised. I would have expected the equivalent of factor(.Internal(col(dim(x))), labels=colnames(x, do.NULL=FALSE, prefix=""))> sessionInfo()R version 2.8.0 Under development (unstable) (2008-05-13 r45682) x86_64-unknown-linux-gnu Martin -- Martin Morgan Computational Biology / Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N.
