[R] thickness of tick marks

[Prof Brian Ripley]

It is par(lwd)
            ^
The device's current setting of par(lwd) does not affect that used by 
axis() (as called by some plot methods).  So you have to call axis() 
yourself.  ?axis would have told you the default was 1.

There was a wishlist item on R-bugs (PR#7223) to change this recently, and 
some counter-arguments -- search on the R-devel list archives for more 
details.
