similar to: under certain conditions, model.matrix appears to lack one (PR#648)

Dear R Team, # Summary of the problem: setting contrasts as > contrasts(g) <- contr.treatment or > contrasts(g) <- matrix(c(1,-1,0),ncol=1) (i.e. without quotes around `contr.treatment' or `contr.sum', etc.) and fitting an lm model without an intercept results in a model matrix that lacks one column.

Thanks for your reply Nassar. What I really want is to overlay (like add=TRUE) the plots 1 and 2. With plots "at the same screen" I meant overlaid and not one beside the other, i.e., only one plot with all the points (1 to 10) in blue (or any other color), the points 5 to 9 in red and a regression line from points 5 to 9.

Again I would like to express my deepest appreciation to all those working so selflessly on the development of R for us all to use it freely (and it is such a joy to use!)

1. THANK YOU! to all who make R possible. It is a real joy to use. 2. The following may or may not be (minor) bugs, but I thought I'd mention them anyway: (a) model.matrix() seems unduly finicky: it seems to accept only "simple" variable names (x1, but not, say, dframe$x1 or I(x1^2), for example) in its argument. model.frame(), however, has no problem with these. (b) If A is a
