I read a R code on loess regression, here is part of it:

f.lo<- loess(bgs ~ f[,1], span=bw, degree=1)
bsln <- f.lo$fitted

What are their functions: bgs~f[,1] , the ~ and the $ in the next line? thanks

    Tilde ~ creates a formula, $ extracts the fitted element from S3 object (so de-facto list) created by loess. You can find more details in R-intro.
