Calculates the mean for each row (column) in a matrix.
rowMeans2(x, rows = NULL, cols = NULL, na.rm = FALSE,
dim. = dim(x), ...)colMeans2(x, rows = NULL, cols = NULL, na.rm = FALSE,
dim. = dim(x), ...)
Not used.
The implementation of rowMeans2()
and colMeans2()
is
optimized for both speed and memory.
