What is it about qqnorm that does not meed your needs?  Have you 
considered the option "datax=TRUE"?  You can store the results of qqnorm 
using "plot.it=FALSE" and then plot using "plot( ..., axes=FALSE)". 
Then add "axis" manually to label points with probability rather than or 
in addition to standard deviations.

hope this helps.  spencer graves
