assign names to matrix

dear all,

i have a matrix and i dont know how to assign names to this matrix.

given v is 100x5 matrix, and label -> c("A","B","C","D","E")

idealy, names(v) <- label, but it doesnt work for different length

if dimnames(v) <- list(1:nrow(v),label), then names(v) return NULL

any smart ways? thanks in advance.

Lists have names(). Matrices don't have names(). They have dimnames() (or
colnames() and rownames()). You want to use dimnames instead.
