I found the answer myself.
'.Fortran("baklo",' in lo.wam() and .Fortran("bakfit",in
s.wam() may carry out backfitting. But I cannot
create an R code which gives the same results as those of
"bakfit". If someone knows the detail of "bakfit" algorithm,
The source code for both Fortran routines is in the package. If I recal correctly the book by Hastie & Tibshirani has descriptions of the algorithms they used. -thomas Thomas Lumley Assoc. Professor, Biostatistics tlumley at u.washington.edu University of Washington, Seattle

You may have a binary install of the package; you need the source. Look in http://cran.r-project.org/src/contrib/gam_0.98.tar.gz, files gam/src/backfit.f and gam/src/backlo.f Duncan Murdoch
