latex for xlab

Hi all,

I don't find the solution to my problem .
I represent  some points and i would like  a title for  the x axis.

I would like to write log_2 where 2 is a subscript of log.
I think  i have to use the functions parse or expression but i have some
difficulties
to understand how i should use them.

See 
 ?plotmath

Use it as in
 plot(1:10, xlab=expression(log[2]))
