Function transforms a set of predictors into a set of predictors, their squares and pairwise interactions
quadr(A, n = 1000)
Returns the predictors including their squares and pairwise interactions
set of predictors
first n predictors, whose interactions with the rest should be taken into account, defaults to all of the predictors
n
quadr(cbind(1:100,rnorm(100),runif(100),rnorm(100,0,2)))
