Dear Lister, Is there an interface in R with SQL server that allows me to append records to table in the DB? Might I do that using RODBC? Thanks a lot. -- WenSui Liu A lousy statistician who happens to know a little programming (http://spaces.msn.com/statcompute/blog)

I have a reasonable grasp of SQL and have experience with MySQL and RODBC but don't know anything much about Microsoft SQL Server.

Hi All, I'm learning JGR 1.4-15 with R 2.4.1 in Windows XP (all patches applied). JGR looks great but I'm having trouble getting the data editor to save my results. I don't see anything in R-help about it. Here are the steps I followed: 1. I chose "Tools>Object Browser" & double-clicked on a data frame, "mydata". 2. A spreadsheet editor popped up and

Well, I downloaded the install JGR package for Windows and that seemed to work fine, after the installation I ended up with a modified R window which looked nice and uncluttered. Which I like. Very much. On the other hand, I cannot see how to launch the thing again once I have closed that window. There is supposed to be a launcher somewhere (JGR.exe?), but I have not been able to find it.
