Questions about glht() and interpretation of output from Tukey's in multcomp
Hi, I have a few questions about glht() and the interpretation of output from Tukey's in multcomp package for lme() model.

Placement of attributes
In preparing data sets for the lme library, I bring the data into R, convert it to the groupedData class, which is an extension of the data.frame class, and use "dump" to create an R-readable version. To cut down on the size of these files I convert the row.names attribute from expressions like c("1", "2", ..., "54") to 1:54. I have run into a curious
