I couldn't find this file. Do you mean corStruct.R, or maybe corStruct.c? > I now want to know how can I use this modified nlme_3.1-96.tar.gz file in R > 2.10. How do I convert this source code into a package? The source code, along with the documentation, data files, etc. _is_ the package. When the package contains source code from a compiled language (C or Fortran), as nlme does, this code must be compiled for your platform before the package is installed. The CRAN maintainers kindly pre-compile this code for Windows and Mac OS X users. If you make modifications to C or Fortran code in a package, you must re-compile the code yourself, or use a service such as R-Forge. The R manual `Writing R Extensions` is the standard reference for packages. See also the `R Administration and Installation' manual. See the information here http://www.murdoch-sutherland.com/Rtools/ for compiling package code in Windows. Lastly, before you follow the instructions at the URL above, I urge you to consider GNU Linux as a platform for programming. I've found the tools available in standard GNU Linux distributions (such as that available at http://www.debian.org) much simpler to install and work with. > > > I have looked on the internet and tried using cmd.exe then the code > Rmcd.exe INSTALL -1 ~/nlme_3.1-96.tar.gz > I end up getting the message "The system can't find the specified path", > when I have the file in the directory that Rmcd.exe is in. > > -- Matthew S.
