Hi Sarah,
Thanks for your very lucid explanations.
Thanks also to David and Dennis.
I got it completely. I now have some nice ggplot of a couple ecdf in
my paper :-)
Now on to do some matrix plots of correlation matrices and some lm().
I'm like a child in a candy shop. :-)
I'm learning something
Thanks for the clarification. I stand corrected.

David is right. I am looking for the ecfd for fs$numstudents. The
other column is just an id.
I guess I don't know how to read the R documentation when it comes to functions.
looking at the documentation, i now notice that it says "Compute an

Dear friends,
Ecdf used to work nicely before.
e.g.
ecdf(df1v[,c(1:6)],group=df1v$trt,q=.5,col=1:2,label.curves=list(keys="l

but now it does not work at all, even for a simpler code??? By the way,
I used the same libraries.
