...mally distributed, hoping that with 120 plants total (6 in each 20 blocks) I could get all kind of sizes for every treatment. It worked ok. I have been trying to analyze this with lme (library NLME). I am not quiet sure which are my random variables. models I have used are: m<-lme(log(fitness)~seedsize*density,random=~1|plot,data=dataset) m<-lme(log(fitness)~seedsize+density+water,random=~1|plot,data=dataset) I have also tried to include plot and water as random effects: m<-lme(log(fitness)~seedsize+density+water,random=~1|plot/water,data=dataset) I am actually not sure if I am using th...

...nts (with 0=dead 1=survivors) First, I want to make a survival object with Surv() but apparently this function only takes two intervals of time (time, and time2).
