It depends on what kind of plot etc and which package you are using. The basic plot routines are summarized in ?plot.default with many of the parameters controlled by ?par
I think at the simplist something like this would work and you can add colour plotting specs etc as you experiment. This assumes col1, c2 and col3 are separate vectors. plot(col, col2) lines(col1,col3) The package ggplot does very nice graphs but completely differently :) --- On Fri, 4/30/10, William Clapham <william.clap...@ars.usda.gov> wrote: > From: William Clapham <william.clap...@ars.usda.gov> > Subject: [R] Newbie question > To: r-help@r-project.org > Received: Friday, April 30, 2010, 10:42 AM > If I have 3 columns of data, col 1 = > Independent Var; cols 2 and 3 are Dep. > Vars.
