Sorry Folks, I'm sure I could suss out the answer myself but I need it soon ... !
1. Given a set of 4 variables X,Y,Z,W in a dataframe DF, I make a scatter-plot matrix using splom(DF). 2. I do all regressions of U on V using lm(U~V), where U and V are all 12 different ordered pairs from X,Y,Z,W. 3. Now I would like to superpose the regression lines from (2) onto the corresponding panels from (1). (By the way, the data used for the regressions are not quite the same as those used for the plots, since a few observations are omitted from the regressions but appear on the plots, so (1) and (2) really are separate operations).
