Thank you for your example. I have successfully modified it with regard to most
fields. However, I think that am not going to be putting this out for my
students. The class I am currently teaching is in multivariate statistics (both
methods and applications, with R used for computing) and I use the opportunity
to provide students with experience in handling different kinds of files. From
what I can tell, this file is being read in using string operations and that is
not peculiar to lisp code.
Best wishes,
Ranjan
