partial residual plots

Dear Dwayne,

I didn't see your post until now, because our email system was down all day
yesterday.

Mark Difford has already pointed your towards the cr.plots() and
ceres.plots() functions in the car package.

In your description of what you want to do, you mention the "adjusted
explanatory variable." This sounds more like an added-variable plot than a
component + residual plot (although the vertical axis of the AV is not the
partial residual). In any event, AV plots are not recommended as diagnostics
for nonlinearity.

I hope this helps,
 John
