Dear Francisco, >From ?scatterplot:
"reset.par: if TRUE then plotting parameters are reset to their previous values when scatterplot exits; if FALSE then the mar and mfcol parameters are altered for the current plotting device. Set to FALSE if you want to add graphical elements (such as lines) to the plot." Best, John ------------------------------------------------ John Fox Sen.
