R help - Sep 2003 - Plotting multiple lines

Hi,

I have a data set with 7 years worth of data, and 2 different values (a real 
value and a model value) of interest in each year for different lengths.  I 
would like a plot with the year on the y axis and an animal length along the 
x axis.  For each year I would like to see two lines, one representing real 
data and one representing model data.  I would like either the model or real 
line to be red.

I have no idea how to start this.  Can anybody help me??  If I didn't 
explain it well enough, I can try to explain it better...

Thank you,
Kay

One way to do it is with barplot.  You would put your data in a
matrix m1 in which the columns were animals and the rows were
real/model.  (I might have it backward about rows/columns).  The
something like barplot(m1,beside=T) and lots of other options for
labels, colors, line thickness, line spacing, etc., although red
just might turn out to be the default.  Look at the help for
barplot.
