Hello Tristan,


I think your problem may be a different one. See item 5 of my
R installation notes below. (I copy the whole lot as other items
may be of interest also.)

The ReadMe.txt file of the Darwin installation says this:
"If R asks for a 
version of any of these dylibs which is named slightly differently
(for instance libz.1.dylib), then just put in a symbolic link in /sw/lib,
i.e. "ln -s libz.1.1.3.dylib libz.1.dylib"."

This is what I had to do to make R work.

Regards,
David.

1. Installed the binary files for R-1.4.0 today (now Thursday).
2. tried to run it today, got dyld errors.
3. Copied all the .dylibs into /sw/lib, as instructed.
4. Got dyld errors again.
5. Made symbolic links as instructed.
6. Now works, but gives runtime error:
/usr/local/R-1.4.0/lib/R/bin/pager: no such file or directory: /sw/bin/less
7. Fixed this by putting the correct path to "less" in
/usr/local/R-1.4.0/lib/R/etc/Renviron
8. Now get postscript error.
9. Restart then OK.
10. Forgot to say that I tar'd the /sw/lib directory, and it is (I hope)
in this here directory now.

1. Tried to install the "as.date" etc. functions in the "date" package,
as follows:
(a)  Got date_1.2-12.tar.gz on desktop.
(b)  R CMD INSTALL date

2. Got errors saying gcc not found - actually need to pick up cc.
3. Tracked down the problem to
	/usr/local/R-1.4.0/lib/R/etc/Makeconf
.. so copied this to Makeconf_as_installed and edited original
to change "gcc" to "cc" in both places.

4. Got another error, saying couldn't find perl.
5. Tracked down the problem to
	/usr/local/R-1.4.0/lib/R/etc/Renviron
.. so copied this to Renviron_as_installed and edited original
to change "PERL=${PERL-/usr/local/bin/perl}" to "PERL=${PERL-/usr/bin/perl}"
at its only occurence.

6. Installation then OK.

7. Ran R, did "library()" and saw "date" was there. Did "library(date)" and
accessed the date things OK. Can now do things like:

> mdy.date(10,29,65)
[1] 29Oct65

> mdy.date(4,9,2002) - mdy.date(10,29,65)
[1] 13311

> as.integer( mdy.date(10,31,1970) )
[1] 3956
