Thanks for your help,
I had read those web pages already, and the post you referred to
already.
So I will try to give more details to what I have done till now
First I must mention again that I am using a mac under tiger. So I
am using .so files.
My fortran file is called kmeans.f, and my subroutine or wrapper I
named it "wrapper"
There is my first line of code
subroutine wrapper(n, p, nran, mat, ishort, w, z, ntran, istand,
k1, k2, iassign, iseed)
In the terminal:
R CMD SHLIB ~/Desktop/Fortan_kmeans/kmeans3.fg77
-fno-common -g -O2 -c /Users/sebas/Desktop/Fortan_kmeans/
kmeans3.f -o /Users/sebas/Desktop/Fortan_kmeans/kmeans3.o
gcc-3.3 -bundle -flat_namespace -undefined suppress -L/usr/
local/lib -o
/Users/sebas/Desktop/Fortan_kmeans/kmeans3.so /Users/sebas/
Desktop/Fortan_kmeans/kmeans3.o
-L/usr/local/lib/gcc/powerpc-apple-darwin6.8/3.4.2 -lg2c -
lSystem -framework R
The files append to compile without any warnings.
In R:
> dyn.load("/Users/sebas/Desktop/Fortan_kmeans/kmeans3.so")
> getLoadedDLLs()
Filename
base
base
grDevices /Library/Frameworks/R.framework/Resources/library/grDevices/
libs/grDevices.so
stats /Library/Frameworks/R.framework/Resources/library/
stats/libs/stats.so
methods /Library/Frameworks/R.framework/Resources/library/
methods/libs/methods.so
kmeans3 /Users/sebas/Desktop/
Fortan_kmeans/kmeans3.so
Dynamic.Lookup
base FALSE
grDevices FALSE
stats FALSE
methods FALSE
kmeans3 TRUE
Dyn.load seems to work since if I type in getLoadedDLLs() I can see
the link.

Erreur dans .Fortran(symbol.For("wrapper"), n = as.integer(n), p =
as.integer(p), :
nom de fonction "Fortran" absent de la table d'allocation
Even so I am using in the name parameter of the .Fortran function,
"wrapper", "kmeans3", "wrapper_" or "kmeans3_"
I always get the same error call telling me that the fonction
"Fortran" is not in the allocation table
That is where I am at now, it has been 4 days I am digging into docs
but I haven't been able to find what I am doing wrong.
R is so great, I got tons of Fortran lines and subroutine to
implement in R but I guess I am missing a little thing to make it
work and now I really don't have a cue how to solve that problem.
Cheers
I will be anxiously waiting for any reply
