Can APL ver 5 handle new R version 2.10.0 (2009-10-26)?
R version 2.9.2 does work on APL.

'r' …SETUP 'R_HOME' '/Library/Frameworks/R.framework/Resources/'
Could not load library for architecture 'r'
LOGICAL UNIT NOT FOUND
'r' …SETUP 'R_HOME' '/Library/Frameworks/R.framework/Resources/'

The first thing to check is whether the R shared library is in the expected place. If that file is not present, the LOGICAL UNIT NOT FOUND error will be signalled.

Under MacOS, the APLX R interface looks for the R libraries here:

Library/Frameworks/R.framework/Libraries/libR.dylib

If you built R 2.10.0 from source, this might not have been installed. You need to specify the option --enable-R-shlib when running the R configure script.

If that isn't the problem, let us know and we'll investigate further.

Thanks.
I checked the recent R version 2.10.0 installed in my mac. This one comes from the http://cran.r-project.org/. I can find the file libR.dylib.

iMac2:Libraries kamakura$ pwd
/Library/Frameworks/R.framework/Libraries
iMac2:Libraries kamakura$ ls
i386 libRblas.vecLib.dylib libreadline.5.2.dylib
libR.dylib libRlapack.dylib libreadline.dylib
libRblas.0.dylib libgcc_s.1.dylib ppc
libRblas.dylib libgfortran.2.dylib x86_64

Please investigate the connectivity with the recent R version 2.10.0.

We tried installing R Version 2.10 on a machine here, and we were able to reproduce the same problem that you are encountering. It seems to be the case that the R interface is expecting 2.9 for some reason. We are still investigating why this is.

In the meantime, there's a fairly easy workaround. Try using the Terminal application, and type the following two commands at the Unix prompt:

Code: Select all

cd /Library/Frameworks/R.framework/Versions/
ln -s 2.10 2.9


This puts in a temporary link so that Version "2.10" can be accessed by APLX using the name "2.9".

You should now be able to use R v2.10 from APLX:

       'r' ⎕SETUP 'R_HOME'  '/Library/Frameworks/R.framework/Resources/'
       r ← 'r' ⎕new 'r'
