final stages of installing R - please help?
Hello,
This morning I downloaded, unzipped, and compiled the latest version of
R for unix, in my HOME/APPLICATIONS directory.
My current unix machine is a sparc-sun-solaris2.9, running SunOS 5.9.
Here are the last few lines of the output following ./configure:
R is now configured for sparc-sun-solaris2.9

matrix inverse in C
Hi,
I'm writing an R package using the C code i've written. I'm wondering if
anyone knows an easy way to calculate an inverse and cholesky factor of a
matrix using the Fortran/C library of R: and how to call them from C. My
code is based on the Numerical Reciepe code, and I'm trying to use
something that is already in R.
Thanks for your help in advance,
Kosuke

R: Re: chol( neg.def.matrix ) WAS: Re: Choleski and Choleski with pivoting of matrix fails
It works! But Once I have the square root of this matrix, how do I convert it
to a real (not imaginary) matrix which has the same property? Is that
possible?
Best,
Simon

R: RE: R: Re: R: Re: chol( neg.def.matrix ) WAS: Re: Choleski and Choleski with pivoting of matrix fails
Thanks for your message!
Actually it works quite well for me too.
If I then take the trace of the final result below, I end up with a number
made up of both a real and an imaginary part. This does not probably mean much
if the trace of the matrix below givens me info about the degrees of freedom of
a model...

R: Re: R: Re: chol( neg.def.matrix ) WAS: Re: Choleski and Choleski with pivoting of matrix fails
Dear Peter,
thank you very much for your answer.
My problem is that I need to calculate the following quantity:
solve(chol(A)%*%Y)
Y is a 3*3 diagonal matrix and A is a 3*3 matrix. Unfortunately one
eigenvalue of A is negative. I can anyway take the square root of A but when I
multiply it by Y, the imaginary part of the square root of A is dropped, and I
do not get the right answer.

Cross compiling a package for Windows on Linux
I would like to compile for Windows a rather simple R package that
contains some C code. It does not contain any Fortran code.
I tried the cross-compilation route using the pre-built set of tools
from http://www.devolution.com/~slouken/SDL/Xmingw32/, as described in
$R_SRC/src/gnuwin32/INSTALL
Using the sources in r-devel from the rsync site I am able to build

problems compiling R-0.63.3 on alpha
Hi again !
Thanks for the info on updating the config.site file which I
have done. I have also added -lm in the Makeconf manually
because this is needed explicitly for DEC cc.
However, there are still a few problems when linking some
of the files as you can see from the enclosed log.
Ciao,

Compiler v10.1.0.0 from IBM). I am still experiencing difficulty in
running "make" after a successful "configure". Any additional insight
you could provide would be greatly appreciated. Output of make is as

I wonder if somebody has a compiled version he could
email me as tar.gz. Many thanks in advance.

It claims to have problems perl (which has worked fine so far)
but in practice it is not only a documentation problem:

Dear list,
This is my first time trying to set up the development version of R
(R-devel ) in my local machine to test some packages before submitting
them to CRAN. I'm using Linux Mint 17.1 64-bit, which is an
Ubuntu-based distro.
However, I'm not able to correctly set up r-devel, apparently due to a
problem with enabling the shared library support.
