nested ANCOVA: still confused
...rbanization (purban) effects on chick health (rtot) and if there are differences between sexes (sex) and the effect of being in the same clutch (box). The model is rtot = sex + purban + (chick)box. I've loaded the package lme4. And the code I have so far is bb <- read.csv("C:\\eabl\\eabl_feather04.csv", header=TRUE) bb$sex <- factor(bb$sex) rtot.lme <- lme(bb$rtot~bb$sex, bb$purban|bb$chick/bb$box, na.action=na.omit) but this is not working. Any suggestions would be greatly appreciated. Thanks, Jeff **************************************** Jeffrey A. Stratford, Ph.D. P...
