Re: [R] Creatiing an R package for solving nonlinear system of equations was: RE: finding roots of multivariate equation

This seems useful, but it is important to note that the approach may not work well unless the system of nonlinear equations is very well behaved and a good starting point is chosen. A good explanation of the problems with this exact approach, that is adding up the sums of squares of the individu

Re: [R] 64 bits machines

Yes, we have an SGI Altix that is similar and R installs just fine. You should be able to compile the source code with either the gnu or Intel compilers. See the R Installation and Administration manual at http://www.cran.r-project.org/doc/manuals/R-admin.pdf, and pay particular attention to th
