Ran into the follow intermediate case in an external package (w/ recent R v2.8.1 patched and R v2.9.0 devel):
> x <- 1:2 > dim(x) <- 2 > dim(x) [1] 2 > x [1] 1 2 > str(x) int [, 1:2] 1 2 > nrow(x) [1] 2 > ncol(x) [1] NA > is.vector(x) [1] FALSE > is.matrix(x) [1] FALSE > is.array(x) [1] TRUE > x[1] [1] 1 > x[,1] Error in x[, 1] : incorrect number of dimensions > x[1,] Error in x[1, ] : incorrect number of dimensions Is str() treating single-dimension arrays incorrectly? What does it mean to have a single dimension this way? Should it equal a vector? I am aware of "is.vector returns FALSE if x has any attributes except names". /Henrik ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
