[R] Literature analysis

Fri Dec 11 16:44:45 CET 2009

OK Thanks again for the help.

I have tried 

example <- read.csv(/PATH/test.cvs)

If i call for the results R is plotting all the data separated by title,
Keyword, author...)

However, I dont know how to tell R that it just should look for e.g.
author,keywords and year and how to plot these for example on x axis the
author and y axis the keywords and on z axis the year?
