Dear R-users, I would like to use Cluster 3.0 for my data because of its zooming, link out and copy (gene)labels into clipboard options.

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?
