That problem is at least two-fold:
1. A failing heuristic in glmnet/configure.in
2. glmnet/src/glmnet/src/newGLMnet_f.f90 does not compile.
Several problems:
- gfortran does not recognise lines starting with [c|C]
comments
- starting at line 517, a line number column was inserted
after column 72
- long lines had been wrapped by inserting [*], often inside
parameter names
-> looks very wrong, much like a listing file
Quick fix procedure:
ad 1. unpack the archive
apply the patch shown below or edit configure.in (replace ${FC}
by ${F77} in line 38)
delete glmnet/configure
repack the archive
try to install the newly packed archive via R CMD INSTALL (will
fail)
ad 2. I could also attach a patch also for glmnet/src/newGLMnet_f.f90
- but it is rather big (you may contact me)
- while the package will compile and load without error,
running example(glmnet) results in:
glmnet> fit1=glmnet(x,y)
Error in validObject(.Object) :
invalid class "dgCMatrix" object:
length(Dimnames[[2]])' must match Dim[2]
In addition: Warning message:
from glmnet Fortran code - Convergence for 1th lambda value
not reached after
maxit=100000 iterations; solutions for larger lambdas
returned
So there seem to be many problems worth of a bug report to the author(s) of
glmnet.
Kind regards
Hugo
