Two things:
(1) type="l" won't work; plot.ecdf() calls plot.stepfun() and it
doesn't have a ``type'' argument.
(2) Giving plot two separate objects to plot makes no sense at all.
(3) If you've got ***frequency*** data then ecdf() is probably not
the right thing to do
in the first pla
Hi r-users,
I would like to compare the cdf between historical and predicted. My x.obs and
x.pre are the frequency data in classes of 0-300.
I tried:
plot(ecdf(x.obs),ecdf(x.pre),type="l",col="red")
and it gives me:
Error in plot.stepfun(x, ..., ylab = ylab, verticals = verticals, pch = pch)
2 matches
