Getting the latest version of R is strongly recommended. The suggestions below all assume the latest version and may or may not work if you do not upgrade.

You may need to put these at the beginning of the path rather than the end. Also just as a check enter

at the console to make sure that you have them. You will likely have to start a new console session and possibly even reboot.

Also you need the Microsoft Help Compiler, hhc. Suggest you reread the material on which tools you need.

In MyRPackages you would have a folder called example, in your case, that contains the package. Within folder example, you would have the DESCRIPTION file, the R folder, etc.

You don't have to run R first. You do need to make sure that R.exe can be found on your path or else use the absolute path name in referring to R. For example, if your path does not include R you could do something like this:

cd \Program Files\R\rw2010
bin\R cmd install /MyRPackages/example

Be sure to use forward slashes where shown above and backslashes where shown.

Try all these suggestions including upgrading R and if that does not work try posting screen dumps of the actual errors you are getting. mailing list PLEASE do read the posting guide! Received on Mon Jun 06 12:32:11 2005
