Hi all, Say I fit a linear model, and saved it as 'test.lm' Then if I use plot(test.lm) it gives me 4 graphs How do I ask for a 'subset' of it?? say just want the 1st graph, the residual vs fitted values, or the 1,3,4th graph? I think I can use plot(test.lm[c(1,3,4)]) before, but now, it's not working... Every time, it goes to the end, the only thing I can click is 'next', it is impossible to save them individually.... I am using xp sp3, R 2.12.

There may be an easier way to do this, but you could always just do it the long way. Ex. plot(residuals(test.lm)~fitted.values(test.lm)) Andrew Miles On Nov 16, 2010, at 5:01 PM, casperyc wrote:> > Hi all, > > Say I fit a linear model, and saved it as 'test.lm' > > Then if I use plot(test.lm) > > it gives me 4 graphs > > How do I ask for a 'subset' of it?? > > say just want the 1st graph, > the residual vs fitted values, > > or the 1,3,4th graph? > > I think I can use plot(test.lm[c(1,3,4)]) before, > > but now, it's not working... > > Every time, it goes to the end, the only thing I can click is 'next', > it is impossible to save them individually.... > > I am using xp sp3, R 2.12. > > Thanks! > > casper > -- > View this message in context: http://r.789695.n4.nabble.com/plot-linear-model-problem-tp3045763p3045763.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help at 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.
