I've been using par() to check the graphics parameters associated with both plot(<fitted linear model>) and plot(<grouped data object>). AFAIK the only differences are in the $cxy, $usr, $xaxp, and $yaxp parameters but the background color for the grouped data plot is grey while the linear model plot has a white background.
When I've tried par(bg = "white") prior to using the plot(<grouped data object>) command it doesn't seem to make any difference. How can I change the grey background to something else? Much thanks in advance, David Paul ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
