Hi there, I have a question regarding the "plot" command after estimation. Specifically, I estimate a model, say regressing y on x and z. And after estimation, I would like to plot the fitted values against x, but I don't need that for z. The following command always gives two graphs, for both variables x and z. plot.np<-plot(model, plot.errors.method = "asymptotic") My question is, what option should I specify in order to get the graph for x only?
Pick a constant value for "z" and vary "x" in a dataframe that you offer to the newdata argument of predict.
?predict Then plot those values versus x.
I know this is probably a very simple question, but I searched around for a while without any luck. Thank you for your time.
