View Matrix contents

What is the R command to view contents of a matrix?

View(myMatrixName) just shows the dimension info.

thanks.

Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers. Not necessary here, though.

I'm going to create a matrix out of an always loaded data set and display it. And show the results in a reprex

m <- as.matrix(mtcars)
