R help - Mar 2008 - Axes in polymars

Hi All,

I can't quite figure out how to change the parameters of the x and y
axes when I plot a polymars object.  I want to add a scatterplot of the
data points, but the polymars plot seems to automatically set the
parameters to fit the polymars line.  I've tried using
plot(poly,1,figc(x1,x2,y1,y2)) but have no luck.  Any thoughts?

Thanks,
Ryan

If I understand what you mean by parameters, see the xlim and ylim
arguments to plot.polymars(). So say you want the x and y axes to range
from 0 to 1:

x.lim <- y.lim <- c(0,1)
plot(poly, 1, xlim = x.lim, ylim = y.lim)

If you have data then try range() on the x and y values respectively and
store the results as your x and y limits.
