Re: [R] plotting regression line in with lattice

Weidong, thanks for the suggestion, but i also need to show to which trt each point belongs to. I had my problem solved by the way. I've been told to add a group subscript object within the panel function, and than use panel.points to plot the original data as data points and panel.lines to dra
