[R] stepAIC: plot predicted versus observed

[sergeetienneparent]

Hi,

stepAIC generic plot function creates useful graphics for the diagnosis of
multiple regressions. To create predicted versus observed plots, I use to
look for the coefficients, copy them by hand, calculate R², then plot. Is
there a more automated way to plot predicted versus observed with its
associated R² output using stepAIC, or another function?

Kind regards,
