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!
Regards,
Jinsong
