prest.r
=======

This is an R program written by Daniel E. Weeks
(dweeks@watson.hgen.pitt.edu) that draws out the 
relationship triangles using the PREST output file "prest_out2".  
That is, it will plot the sharing probabilities on the 
'relationship triangle' as described in Elizabeth Thompson's 
book "Pedigree Analysis in Human Genetics".

This program runs fine in Splus as well as in R.  

We added a minor modification so that it works with the output file 
created using either option of PREST.

The program is included in the gzipped tar archive and it can
be also download individually.  The usage is described in the 
program and it is also included in the README file.
