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

I create a matrix of size 3x3 called mat_1 and then I want to iterate over
all the values one by one and print the element as well as the position in
the matrix:
My code is :
mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol =
3,byrow = TRUE)
mat_1
# Loop over my_matrix
for(row in 1:nrow(mat_1)) {
for(col in 1:ncol(mat_1)) {
print(mat_1[row, col])
}
}
But I don't know how to print elements and positions as well of this matrix?
