using compiled fortran in R
See `Writing R Extensions' for the information. R CMD SHLIB hello.f
dyn.load("hello.so")
might be what you need. dyn.load in R loads shared libraries (on Linux), not .o objects. The error message does say your hello.o is not a valid shared library. Looks like the help page for dyn.load needs a cross-reference to SHLIB.

Hi,
I would like to use a Fortran subroutine in R. I have checked the R
docs and Newsletter,
but..., I am unable to load an object file into R.
The steps I have taken are (on Debian Linux/recent Intel-type chip ):
1. g77 -c hello.f
to create hello.o
2. mymachine> R
to start R
3. > dyn.load("hello.o")
at which point I am getting the error msg:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library "/home/hawkins/Rfortran/hello.o":
/home/hawkins/Rfortran/hello.o: ELF file's phentsize not the expected
size
Can anyone (please) correct my procedure, offer a suggestion?
thanks,
Natalie Hawkins
