I would like to get some instructions on which packages of R should I
install. I am intending to use R for graphical analysis, correlaction, and
also estimation - this latter the least, since I have an econometric

Dear all,
I would like to know which is the right way to check the normality assumption
for performing ANOVA. How do you check normality for the following example?
I did an experiment where people had to evaluate on a 7 point scale, the degree
of realism of some stimuli presented in 2 conditions.
The problem is that if I check normality with the Shapiro test I get that the
data are not
