Yes.  Because the 'Subject' of this thread is such common task 
(for some), I had created the function mult.fig() about ten
years ago (in S-plus times).  That is now part of the 'sfsmisc'
package.

After
    > install.packages("sfsmisc")
you can use
    > sfsmisc::mult.fig(4, main = "main title")

and then do your for plots afterwards.
mult.fig() has the other advantage of using slightly smaller
margins for the single plots, by default, so you get more "real
estate" for plotting.
