[R-sig-Debian] aggregate() example fails]

[Michael Rutter]

Kenneth,

example(aggregate) works fine on the amd64 ubuntu packages on CRAN.  You 
are running a slightly newer version (an alpha or beta, I think), which 
may be a problem.  If I get a chance in the next couple of days, I will 
try the new beta to see if example(aggregate) still works.  My 
suggestion would be to use the packages on CRAN.  Is there are reason 
why those are not sufficient?
