Thank you, John, for this bit of information - it will be useful when I move to 64 bit Vista one of these days. FWIW, the Ubuntu 8.10 amd64 install I attempted was on 64-bit versions of everything (except possibly StatET itself). 64-bit R, JDK, and Eclipse. If someone does get StatET working

Re: [R] SUM,COUNT,AVG

I gather you have an SQL background since those are SQL functions. Check out the sqldf R package and the many examples on the home page: http://sqldf.googlecode.com and in ?sqldf That may ease the transition from SQL to R. On Mon, Apr 6, 2009 at 5:37 AM, calpeda wrote: > > Hi, > I ve been sear
