F distribution from lme()?
Dear all, Using the data set and code below, I am interested in modelling how egg temperature (egg.temp) is related to energy expenditure (kjday) and clutch size (treat) in incubating birds using the lme-function. I wish to generate the F-distribution for my model, and have tried to do so using the anova()-function. However, in the resulting anova-table, the parameter kjday has gone from being highly non-signiicant in the lme-expression, to...

Help with repeated measures!
Hello all, I'm an R novice, recently trying to implement R in my research. Using the data frame below, I want to construct a repeated measures model, with energy expenditure (kjday) as dependent of treatment (code) using mass as a covariate. ind mass kjday code 79 15.8 45.216 3 42 16.5 44.64 3 10 14.85 45.216 3 206 15.75 45.216 3 23 12.15 42.336 3 5 14.6 51.264 3 .... 79 16.9 46.944 5 42 16.6 44.352 5 10 15.6 51.552 5 206 15.5 45.504 5 23 12.3 42.336...
