When I perform a two-way anova on my dataframe "pin", I can't get any
indication about the interaction among the two factors "gen" and "con" while
the statistics about the significance relative to the two factors alone is
correct.
I wrote this:

*pvalues_genotipo<-sapply(pin[,1:(length(pin)-2)],FUN=function(x)
summary(aov(x~gen*con)))*

Where is the mistake?
