Installing nloptr on Linux

Question

I am trying to install the R package nloptr on a CentOS Linux machine that doesn\'t have internet connection as follows:

install.packages(\"/hom         


        

Answer 1

When you say [t]his command in turn looks for the following file online you only get half the story. Together with Jelmer, the maintainer of the actual nloptr package, I modified the package to do the following:

• look for an install libnlopt library, and, if found, use it
• if not found fall back to the old behaviour and download the library

So you could simply install nlopt via

 sudo apt-get install libnlopt-dev

(or the equivalent sudo dpkg -i /media/.... pointing to the file from a USB drive etc pp) and then reinstall the nloptr package. It will just work. On my machine:

edd@max:~$ install.r nloptr         ## install.r is in littler

Note how it compiled only two files from the actual R packages having found the nlopt installation.
