Have a question regarding how to accurately put this experimental design in the correct way in R.
I have attempted this before using lme, but eventualy we tried SAS. 

Response variable ~ site + rewetting + tree removal + distance along ditch + distance along ditch*tree removal + distance from ditch/rewetting, random=~1|quadrant/transect/obsplot)).

What puzzled me was that the data I got when using the lme formula was not the same, and I clearly must have written it the wrong way.

There are 3 sites, each treated in a split plot design with rewetting and tree cutting. This results in each site being divided up into 4 different treatment combinations that we refer to as quadrants. Each quadrants has 4 transects, and Each transect has 5 relevees that were monitored. Hence the nesting of the random variable quadrant/transect/obsplot in the end. I would be greatly thankful for any help in what the correct way to write this in R would be. Was I right to go after lme. I thought I was, but obviously the way I put it in lme was wrong.

Any input on this is greatly appreciated.

Best regards, Petter H
