If there a list of changes between 3.1 and 3.0.3 ? For example, when using levels(xxxx), if xxxx was not a factor, in 3.0.3 it was changed as a factor but in 3.1 RC it returns NULL. Same for automatic conversion in numeric for characters used in algebric operations. New way is more strict and is better in my point of view. It will prevent unwanted side effect in code. Thanks a lot Marc Girondot
I would have thought a web search for "R devel changelog" would get you to the right place... Google gives me developer.r-project.org/blosxom.cgi/R-devel/NEWS as the first hit, which looks about right. best, Ista On Mon, Apr 7, 2014 at 1:22 PM, Marc Girondot <marc_grt at yahoo.fr> wrote:> If there a list of changes between 3.1 and 3.0.3 ? > > For example, when using levels(xxxx), if xxxx was not a factor, in 3.0.3 it > was changed as a factor but in 3.1 RC it returns NULL. > Same for automatic conversion in numeric for characters used in algebric > operations. > > New way is more strict and is better in my point of view.

If you don't have it installed, a copy of the nightly news is on CRAN under "new features in this version" on <http://cran.r-project.org/bin/windows/base/rtest.html>. (The actual URL changes sometimes; currently it is <http://cran.r-project.org/bin/windows/base/NEWS.R-3.1.0rc.html>.) The RSS feed that Ista pointed you to will tell you about changes to that file (i.e. sort of second differences to R).
