Anova
Hello, You're thinking of ?aov. anova() does _not_ have a formula interface, it would be anova(lm(HSuccess ~ Veg, data = data.to.analyze)) or aov(HSuccess ~ Veg, data = data.to.analyze) Hope this helps, Rui Barradas Em 05-10-2012 09:27, Jhope escreveu:
Hi R-listers,
I am trying to do an ANOVA for the following scatterplot and received the
following error:
library(car)
scatterplot(HSuccess ~ Veg,
data = data.to.analyze,
xlab = "Vegetation border (m)",
ylab = "Hatching success (%)")
anova(HSuccess ~ Veg, data=data.to.analyze)
Error in UseMethod("anova") :
no applicable method for 'anova' applied to an object of class "formula"
I am wondering if there is a better way to do this?
Please advise, Jean
