Hi all,
I try to utilize RSPython to invoke Python from R. For me it works pretty
fine for basic applications, but I have 3 problems that may be related.
(1) I can't load other packages but "standard" ones also when I adjust the
PythonPath:
> importPythonModule('sys', all=T)
NULL
> importPythonModule('numpy', all=T)
Error in .PythonEval(cmd) :
Error in Python call:
/usr/lib/python2.5/site-packages/numpy/core/multiarray.so: undefined symbol:
_Py_ZeroStruct
> importPythonModule('Scientific.Functions.Derivatives', all=T)
Error in .PythonEval(cmd) :
Error in Python call:
/usr/lib/python2.5/site-packages/Scientific/linux2/Scientific_numerics_package_id.so:
undefined symbol: PyString_InternFromString
(2) I can't even load the test example provided at www.omegahat.org/*
RSPython*/ <http://www.omegahat.org/RSPython/> .
>
Sys.putenv("PYTHONPATH"='/usr/local/lib/R/site-library/RSPython/tests')
> .PythonInit()
> test <- .PythonNew("RSTest", .module="method")
Error in .PythonNew("RSTest", .module = "method") : No such module
(3) It doesn't find RS.so if I try dyn.load("RS.so")
My OS is Linux Debian (kernel 2.6.27-11-generic) .
Many thanks for you help!
David
