Dear all,
I was wondering if anyone could help solve a problem of a missing interaction
effect!!
I carried out a 2 x 2 factorial experiment to see if eggs from 2 different
locations (Origin = 1 or 2) had different hatching success under 2 different
incubation schedules (Treat = 1 or 2). Six e
Hello everyone,
I was wondering if anyone knows of an R package which will extract the
standardised effect size (r) and 95% confidence intervals for a single
continuous predictor in a mixed-effects model. For example, I have
model<-lme(damage~car+depth+wet,random=~1|id,data=data)
I need to fin

Hi Sam,
Just a stab in the dark here, but is your grouping variable really

Dear R Users,
I was hoping for some help with a recurrent error message in lmer. I am trying
to model the effect of temperature on metabolic rate in animals (response =
int.length) at different temperatures (mean.sst), with repeated measurements on
the same individuals (random effect = female).
Yes that worked perfectly. Many thanks.

Hi,
I was hoping to get some advice on how to derive estimates of slopes from four
parameter logistic models fit with SSfpl.
I fit the model using:
model<-nls(temp~SSfpl(time,a,b,c,d))
summary(model)
I am interested in the values of the lower and upper asymptotes (parameters a
and b), but als
