Hi there, I cannot find a detailed explanation to the following error message:
> colnames(matrix(1:10, ncol = 2)) <- c("X", "Y") Error in colnames(matrix(1:10, ncol = 2)) <- c("X", "Y") : target of assignment expands to non-language object However, when I do the following things, the error message disappear: > z <- matrix(1:10, ncol = 2) > colnames(z) <- c("X","y") What's the difference between the two methods? Any comments or suggestions? Thank you very much in advance!
