rowSapply for matrices?

[berndbischl]

How do I do this operation est in R?

• given A matrix A
• I would like to apply a function to every row.
• this function returns a vector (a new row)

I want the resulting matrix.

I think this is what you want.

A = matrix(1:10, 5, 2)
print(A)
fn = function(x) x^2

B = t(apply(A, 1, fn)) # this is what you want
print(B)

Yes, sure.

I just do not find this very readable, especially because of t()

Maybe we should have a REALLY nice family of all apply-variants we want in HELL?
