In R, match function for rows or columns of matrix

Question

The value matching function in R is very useful. But from my understanding, it does not sufficiently support two or high dimensional inputs.

For examp

Answer 1

You could do that without using any functions:

Suppose adj1 is the 3*3 matrix with both colnames and row.names being c('V1','V2','V3') and vec1 is the order you want your matrix to be transformed into:

vec1 <- c('V2','V3','V1')

You could simply using the following code:

adj1[vec1,vec1]

Which will do you the magic.
