Well, as R tells you: You should check, whether your data is of type
"numeric". Depending on the way you import the data "spr" this may not
be the case and you have to do
> density(as.numeric(spr))
which should work... Besides: please read the guidelines for posting
(see http://www.R-project.org/posting-guide.html) giving some details on
the procedure you use to read in the data may have helped to give you a
precise answer!

Winfried
