[R] Repeated Measures

[Redding, Matthew]

Hi R Gurus, 

I am more or less a beginner with R.  I have searched your FAQ, manuals, and
the archives of this list for an answer to this question, unsuccessfully.
I commonly do analysis of chemical characteristics of soils, by depth
intervals (e.g. 0-100 mm, 100-200, 200-300, etc), comparing two soil
profiles that 
have received some treatment (effluent).  In Genstat I can handle this
problem using one of several repeated measures approaches that allow me to
determine if the 
profiles on a whole are sig dif, to determine if one depth interval is
significantly different from another (within the same profile), and to
determine if significant leaching
has occurred from the active root zone.  In genstat the procedures are
Arepmeas, and Antedependence.

Is there a comparable capability in R?

Thanks,
