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
Here are the beginning of a R program.
I hope it can help you writing the rest of the program.

Yes, and the structure is obviously case-insensitive. More troublesome is
probably that there can be multiple ACADEMIC-EMPHASIS entries, which can be
tricky to tidify. Also one would need to figure out what is the meaning of
lines like

The file also has a bunch of email headers stuck in the middle of it:

That's a nice example of why Lisp is both powerful and terrifying - you're
looking at a Lisp *program*, not just Lisp *data*, as Lisp makes no
distinction between the two. You just read 'em in.
The two definitions at the bottom are function definitions. The top one
defines the def-instance funct
Thanks! I guess one way to do it in R would be to read the lines and then do
character parsing (string-matching and other operations) to save as a data
frame and forget about the lines at the end perhaps? I am not sure how general
such a scheme would be: that is also something I would like to sh
Thanks! I am trying to use it in R. (Actually, I try to give my students
experiences with different kinds of files and I was wondering if there were
tools available for such kinds of files. I don't know Lisp so I do not actually
know what the lines towards the bottom of the file mean.(

It seems the file contains records, with each record having 18 fields.
I would use awk (standard unix tool), creating an awk script to process the
file
into a new file with one line for each record, each line with 18 fields,
say comma-separated.
The csv file can then be easily read into R via the f
