Average of each column in a matrix in R

Question

I'm new to R and still learning. I have a matrix with 100 columns and I need to calculate the average of each column and store all those values for further calculations. Each column has 5 numbers and after this step i'm supposed to have 100 new values. Also, please let me know if the replicate() function is a viable way to do this in just one line.

just do `colMeans(your_matrix)` – Onyambu Mar 19 '18 at 02:47 — Onyambu, Mar 19 '18 at 02:47

colMeans(DF)

Is a highly optimized function for exactly this purpose.
