Repeated measures by lme and aov give different results
...significant p-values,
consistent with those I obtain performing this analysis in SYSTAT. Can
anyone explain how these models differ, and which is more appropriate to
the experimental design I have described? The code I use, and the
output obtained follow:
1 lme model
library(nlme)
M5 <-lme(ln_tot_lgth ~ Carbon*O3*Harv., random = ~-1|Ring)
anova(M5, type="marginal")
