Hi Patricia,
This seems to be the "intelligent spacing" problem that often appears on 
the list. If you ask for more than about eight labels on the default 
sized plotting device without also asking for a smaller font size (cex), 
R will tidy them up by ignoring some. You can force the axis labels to 
some extent by using:


If you find that your labels begin to overlap, have a look at the 
staxlab function in the plotrix package.
