Re: [R] extracting intercept from ppr fit Hi,  Is there a way, documented or not, to extract the intercept term (the alpha_0 the MASS book) from a ppr() (Projection Persuit Regression) fit?  Thanks,  Vadim  ## Example:  n <- 1000  data <- data.frame(x=rnorm(n), y=rnorm(n))  a <- 10  data$z <- evalq(a + atan(x + y) + rnorm(n), data)  data.ppr <- ppr(z ~ x + y, data=data, nterms=1)  ## how to extract a = 10 from data.ppr?
