[R] x axis with multhist

[Nathan Clement]

I have lots of data that needs to be viewed as a histogram, and I've  
found the multhist package to work quite nicely--for the most part.   
The only problem is that I can't figure out a way to get the x-axis to  
make any logical sense.  I have a data set with exactly 26 different  
values, but when I try and plot it with multhist, There are tick marks  
at 0.5, 3.5...26.  When I enlarge the screen, instead of changing the  
differences between the smaller values, multhist will simply double  
some of the larger values (ie 22, 24...).
I've tried turning off the axes (I can only get the y-axis to turn  
off), using

multhist(l7,breaks=26,axes=F)

Most of the other arguments (names.arg, lab, even using  
plot(multhist(l7)) ) didn't have any effect on the graph.

Is there any way I could accomplish this?

Thanks,
Nathan
