[R] to print system.time always

[mrzung]

Hi all;

I want to print system.time whenever I execute any command.

It takes too much time to type "system.time()" function to all command.

is there any solution on it?

And,

apply(matrix,1,cumsum) command is too slow to some large matrix.

is there any function like rowCumSums ?

thank u!
