Hi,

My apologies for asking this question, but could not find the answer
elsewhere. I understand the glmnet package uses Fortran code. For example,
the lognet.R file includes the lines of code shown below. But how can I see
the Fortran code that is being referenced in the code below? Is that
provided somewhere in the package source code?

.Fortran("lognet",

parm=alpha,nobs,nvars,nc,as.double(x),y,offset,jd,vp,ne,nx,nlam,flmin,ulam,thresh,isd,maxit,kopt,
          lmu=integer(1),
          a0=double(nlam*nc),
          ca=double(nx*nlam*nc),
          ia=integer(nx),
          nin=integer(nlam),
          nulldev=double(1),
          dev=double(nlam),
          alm=double(nlam),
          nlp=integer(1),
          jerr=integer(1),PACKAGE="glmnet"
          )
Thanks for your help.

Regards,
Axel.
