R paste matrix cells together

Question

I want to paste cells of matrix together, But when I do paste(),It returns a vector. Is there a direct function for same in R?

mat <- matrix(1:4,2,2)
past         


        

Answer 1

Or use sprintf withdim<-

`dim<-`(sprintf('%d,%d', mat, mat), dim(mat))
#      [,1]  [,2] 
#[1,] "1,1" "3,3"
#[2,] "2,2" "4,4"
