Two Factor ANOVA Errorbar plot in R?

Here is another attempt using the sciplot package. Alternative ways to compute the confidence intervals can be passed in parameter ci.fun.

I have to admit I'm quite baffled by your code. Don't take this as personal criticism, but I strongly advise you to learn your students to use the power of R as much as possible. They can only benefit from it, and my experience is that they understand faster what's going on if I don't throw lines and lines of code clutter to their heads.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
