Linux and Unix Binary Installation
----------------------------------
Binary packages for rpy are available for Debian GNU/Linux via the
standard mechanisms.
Other binary packages may be available from the rpy download site.
Linux and Unix Source Installation:
----------------------------
If you have Numeric (NumPy) installed, it can be used by RPy; normally it is
autodetected, you don't have to do anything. If Numeric cannot be found, then
R arrays will be converted to Python lists, which are a lot more inefficient
than Numeric arrays. I strongly suggest to install Numeric.
If you have installed some previous version of RPy, just go to (c).
To install RPy follow the steps:
(a) First of all, you *must* check that you have built R with the configure
option '--enable-R-shlib', in order to make R as a shared library. If
not, the following steps should be enough:
<go to the R source directory>
make distclean
./configure --enable-R-shlib
make
make install
(Solaris users, please, see the note (a) below.)
(b) Then, configure the path to the R library. You have several ways to do
this (substitute RHOME with the path where R is installed, usually
/usr/local/lib/R):
o make a link to RHOME/bin/libR.so in /usr/local/lib or /usr/lib, then
run 'ldconfig',
o or, put the following line in your .bashrc (or equivalent):
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:RHOME/bin
o or, edit the file /etc/ld.so.conf and add the following line:
RHOME/bin
and then, run 'ldconfig'.
(c) Now, just type:
python setup.py install
and that's all!
If you want, you can run the regression tests located in the 'tests'
directory, just read the README file in that directory. For a quickier test,
launch the Python interpreter and import the module 'rpy':
Python 2.2 (#2, Dec 23 2001, 16:30:35)
[GCC 2.95.4 20010703 (Debian prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import rpy
>>>
If you get some error, refer to TROUBLESHOOTING below. If you want to test
the module without installing it, do:
python setup.py build
Then, cd to build/lib.<platform>-<version>/ and try to import the module.
*** NOTES ***
(a) Solaris users must change the line:
LIBR_LDFLAGS = -shared
in the file 'Makeconf' on the R source directory, for the line:
LIBR_LDFLAGS = -shared -symbolic
before recompiling the R library.
(b) It has been reported that it may be necessary, in some situations,
to completely remove the R sources, to unpack it again, and to
compile to R library with the new options.
