I am using lme to handle repeated measurements. So far i can follow the examples from the book from pinheiro and bates. Now i get the problem , that i have "nested" repeated measuremnts, and i cant find out how to do the grouping part of the lme formula.
1.The simple problem ist that i have different Samples , from which i make repeated measurements (each sample is measured 6 times) and i repeat this experiment over several Days, so i get the lme grouping term "random=~1|Days/Sample". 2. Now i am measuring with 2 different measuring Apparatus the same Sample each 6 times, to see how big the difference from the appratus is. Because Apparatus is on the level of repeated measurements i cant write Days/Sample/Apparatus. the lme function offers a list() feature to design the grouping, but i didnt understand this, if it is the solution to the problem. Maybe somebody had the same Problem? best greetings N.Busscher -- #--------------------------------------------------- ##!!
