problems compiling R on AIX5.1
Hello,
I'm trying to compile R (versions 1.6.0, 1.6.1, 1.6.2 and 1.7.0) on
our IBM Power3 Machine for an external user.
I always used to configure with
./configure --prefix=/scratch_tmp/harald/instala
I've never achieved to compile 1.7.0 because it seems that a file
called R.exp is missing (or maybe it's not well referenced on the
makefile).
Output of make:

Sample size calculation for differences between two very small proportions (Fisher's exact test or others)?
Hi,
I'm try to compute the minimum sample size needed to have at least an 80% of power, with alpha=0.05. The problem is that empirical proportions are really small: 0.00154 in one case and 0.00234. These are the estimated failure proportion of two medical treatments.
Thomas and Conlon (1992) suggested Fisher's exact test and proposed a computational method, which according to their table

problems compiling R on AIX5.1
Dear all,
after trying to compile R on our IBM Power3/AIX 5.1 machine I've
been able to run it correctly.
First of all I would thank all who responded my mails.
I explain here how I've done it:
First of all, it seems that configure and some shared libraries of

(PR#1289)
Dear all,
I've found a bug report for R when installing it on an AIX5.1 system.
There's a followup (number 4) that comments a segmentation fault on R
when quitting "q()".
I'm using a newer version of R but on the same operating system and
I obtain the same error.
There was a way to solve this problem?
Best regards and thanks,

64bit build on IBM
I am trying to build R with 64bit support so I can access more than
2GB of memory on an IBM running AIX. (IBM NightHawk II RS/6000 node with 16
64-bit, 375-MHz POWER3 CPUs and 32 GB of memory, if you want specifics)
The 32bit install required little tweaking, but the 64 bit is sufficiently
complicated that I thought I would report my findings here and ask for
help with the latest (and hopefully last) hurdle.
Let me also state I have been amazed at the ease of...
