'for' in steps

I want to use 
for (i in 1:time) 

but I want the increments to be monthly.

For example, if I'm adding interest to a virtual bank account monthly, for a
total of 'time' in years which the user has entered.

Is there a simple way of doing this please? I'm not familiar with many R
functions yet.
