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?
anova() needs a model object, not a formula, as its first argument: anova(lm(HSuccess ~ Veg, data=data.to.analyze)) Alternatively, you can use aov(), with summary(), to get the ANOVA table: summary(aov(HSuccess ~ Veg, data=data.to.analyze)) I hope this helps, John ------------------------------------------------ John Fox Sen.
