hi Andrew Many thanks for the suggestion. I gave it a try , but still get the same issue - a fresh Rgui window (just one) opens, with an empty .RData, when I submit a script ( Ctrl & F8 ). I also tried running things as administrator, but it made no difference. Apparently windows 7 is selling like hot buns, so there should be enough market pressure before too long , to encourage the providers of Notepad++ NpptoR to fix it ... Thanks again Bob Robert Kinley bobk@lilly.com Andrew Redd <aredd@stat.tamu.edu> Sent by: amredd@gmail.com 04/03/2010 14:17 To Robert Kinley <KINLEY_ROBERT@lilly.com> cc Subject Re: [R] running R from Notepad++ in Windows 7 I had a conversation with someone the other day about problems on Windows 7. It was caused by the compatibility mode that they were running R in. That might be the issue here if you are using compatibility mode. Run NppToR and R both in compatibility mode and that should fix it, if that is the problem. Just to make sure though, does it open a new session for every line of code or does it launch once then continue in that window? For fixing the problem it will help me to know.

On my work XP machine , it runs fine in an already-open Rgui window 2. On my home Windows 7 machine, it ignores the existing Rgui window and fires up a fresh one, which doesn't use the same .RData, so it fails. Anyone else hit this and, ideally, solved it ... ? cheers Bob Robert Kinley bobk@lilly.com [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
