R help - Oct 2011 - Perform 20 x one-way anova in 1 go

Hi Guys,

I have about 20 continous predictors and I want to do one-way anova to check the
significance of each variable against the dependent variable.
Apart from doing running the anova 20 times, is there a faster way?

Thanks,
Joshua

This is one solution

?sapply

sapply(data.frame(iris$Sepal.Length, iris$Sepal.Width,
iris$Petal.Length, iris$Petal.Width), function(x)
(summary(aov(x~iris$Species))))
