I get the following error message when I try to make a heatmap (package stats), without the associated dendrograms.

X <- matrix(rnorm(200),20,10)
XX <- crossprod(X)
heatmap(XX, Rowv= NA, revC=TRUE)
Error in rev(ddr) : object "ddr" not found heatmap(XX, Rowv= NA, sym=TRUE)
Error in heatmap(XX, Rowv = NA, sym = TRUE) : object "ddr" not found  

According to the help file, this should work; indeed it does if I set revC or sym to FALSE. Seems like ddr should be initialized to something like 1:ncol(X) for the no-dendrogram case.

Kind regards,
