R help - Aug 2015 - Error in rep in matrix - Windows 8- R 3.2.1

y <- matrix(rep(10,4),2,2)
> y
     [,1] [,2]
[1,]   10   10
[2,]   10   10



I expected an output of
> y
     [,1] [,2]
[1,]   10   4
[2,]   10   4



Thanks and Regards.

When you get something you don't expect, you should start by examining the
arguments. Type this at your console:

rep(10,4)

It should then be obvious that you need to read the help page for `rep`.
