[R] Discriminant analyse

[Benedikt Niesterok]

Hi everyone,
I intend to do a discriminant analyse for 2 measures(eye diameter and body length) and for different areas to show differences between those areas if there are any. The raw data (eye diameter, body length) make one cloud of points so it seems there aren't any differences between those areas.
If I take the mean values (eye diameter) for length classes, I nearly get
linear functions that differ in slope and intercept.
The question is:
Can I do something like a discriminant analyse for those lines to statistically separate them from each other or is there a totally different method for this case.
If you know any method, please, could you let me know.
Thanks,    Ben
