Get matrix of minimum value from two equally sized matrix

Question

I've looked everywhere but could find an answer.

I have to numerical matrix a

1 2 3
4 5 6

and b

3 1 4
5 2 1

and would like to get c equal to the minimum pairwise values of a and b

c

1 1 3
4 2 1

Thanks

Sorry I edited the matrix to be more specific. My actual matrices are huge so I need an efficient way to do it. Thanks — henri vanhomwegen, Nov 30 '18 at 07:49

You can use pmin, i.e.

pmin(m1, m2)
#     [,1] [,2] [,3]
#[1,]    1    1    3
#[2,]    4    2    1

DATA:

m1 <- matrix(c(1, 2, 3, 4, 5, 6), ncol = 3, byrow = TRUE)
m2 <- matrix(c(3, 1, 4, 5, 2, 1), ncol = 3, byrow = TRUE)
