How to use the 'sweep' function

df_T=sweep(sweep(df,2,df_means,"-"),2,df_sds,"/")*10+50
This code convert raw scores to T scores (with mean=50 and sd=10):

void invariant(Rectangle r) {
r.setHeight(200)
r.setWidth(100)
assert(r.getHeight() == 200 and r.getWidth() == 100)

However, this invariant must be violated by a correct implementation of Square, therefore it is not a valid substitute of Rectangle.
