head(USJudgeRatings)

personal = USJudgeRatings[,c("INTG","DMNR","DILG","FAMI")]

performance = USJudgeRatings[,c("CFMG","DECI","PREP","ORAL","WRIT")]

a) Compute the canonical correlations

b) Test for the significance of the canonical correlations with alpha=0.01.

c)Generate two plots using the function helio.plot: one plot for cv=1 and one plot for cv=2.
