Oh dear, dangerous terrain ....
Yes, there are some non-free packages on CRAN according to the
terminology used by the Free Software Foundation. One example was
already given in the original question: "mclust". Just read its license
file.
Best wishes,
Uwe
I assumed that CRAN had a
policy of not accepting anything that could not be freely distributed,
but I could not find any such statement in a quick search. The code by
Uwe identified 52 packages with "file LICENCE" or "file LICENSE", plus
others with combinations of something like GPL with "file LICENCE" or
"file LICENSE".
Thanks,
Spencer

Hello Everyone,
Just finished reading A Handbook of Statistical Analyses using R by
Everitt and Hothorn. I'll begin by saying that I quite liked the
book. It's both little and mighty in the sense that it's very compact
but contains a tremendous amount of useful material.
The last chapter of the book deals with cluster analysis. There's a
package used in this chapter (I believe that it's called mclust) that
charges an annual fee to non-academics. I did a little digging and
found out that the annual cost for some one like me would be $100 but
it would cost more for people in large companies. This isn't exactly
outrageous but got me to wondering how many other packages might not
be free. I searched online but didn't find much.
Does anyone have any information about this?
Are you talking about CRAN packages?
If so, looking into the license information of the repository shows
which have standard licenses such as GPL and which licenses are
special. Just take a look, e.g. starting with
download.file("http://cran.R-project.org/web/packages/packages.rds";,
"packages.rds", mode="wb")
x <- .readRDS("packages.rds")
x <- x[!duplicated(x[,1]),]
table(x[,"License"])
Best,
Uwe Ligges
Thanks,
Paul
