...ogramming knowledge, so when I search for answers to my
questions, I struggle with making sense of a lot of the pages.

arguments must have same length
> score<-read.csv("http://users.stat.umn.edu/~chen2285/hw/ACT.csv")
> interaction.plot(sex,rep(1,861),score,fun=mean,legend=F,main="profile of

Error: tapply(response, list(x.factor, trace.factor), fun) :
