Hello John and others,
I’d appreciate your help as I’m trying to plot the effect of predictor “Days”
on Reaction by Subject. I’m only getting one plot in the example below.
### Start example
library(lme4)
library(splines)
data("sleepstudy")
fm1 <- lmer(Reaction ~ ns(Days, 3) + (ns(Days, 3) | Subject), sleepstudy)
coef(fm1)
plot(allEffects(fm1))
### End example
Thanks,
Axel.
