Emil, I've no clue what gam() does nor how it works, but saying that is it possible to use lines(,lwd=???) in someway and plot on top of the original line? cheers, Sean

Sear Sean, here is the more working example (I use the latest version of everything on my PC): x1<-runif(100,-5,5) x2<-runif(100,1,50) e<-rnorm(100) y<-.3*x1-0.5*x2+e mod<-gam(y~s(x1)+s(x2)) par(mfrow=c(1,2)) plot(mod,residuals=T,se=T) -------- So you get two figs. My concern is to enlarge the regression line, not the point or enything else. Best, Emil
Hi Emil, can you give us a working example of what you're trying to do? cheers! Sean ps. as per the posting-guide... :-) On 24/08/05, Tkadlec Emil <tkadlec at prfnw.upol.cz> wrote:
Dear colleagues, I would like to have GAM regression lines (package gam) thicker than the default setting does. Is there any way to change the width of regression line when plotting gam.objects from the package GAM with more than one predictor? Changing lwd parameter in plot function controls all line components, including points making them thicker as well, which is not what I would like to have. Thanks for help.
