[R] Need help to print matrix with element and position

[Rui Barradas]

Hello,

With no loops:


cbind(
   row = c(t(row(mat_1))),
   col = c(t(col(mat_1))),
   mat_1 = as.numeric(t(mat_1))
)


If the matrix entries are not numeric, use cbind.data.frame. This will 
keep the row and column numbers as numbers, the default cbind method 
would coerce them to the class of mat_1's elements.


cbind.data.frame(
   row = c(t(row(mat_1))),
   col = c(t(col(mat_1))),
   mat_1 = c(t(mat_1))
)


Hope this helps,

Rui Barradas
