R-helpers,
Is there an easy way to call an external (C) program using .C or .Call
without including the code in a package. I know how to do it using
system(), but that doesn't seem to be a permanent or portable solution.
Initially I tried:
.Call('filepath.to.c.function', arg1)
and got this error:
Error in .Call("filepath.to.c.function", "arg1", :
"C" function name not in load table
So read the section on foreign language interfaces in the Writing R
Extensions manual but when I tried:
dyn.load('filepath.to.c.function')
I got:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library 'filepath.to.c.function':
dlopen(filepath.to.c.function, 6): bad external relocation length
Do you need to run R_registerRoutines before dyn.load()? I couldn't find
any mention of this error on the web....
