Hello,

I get the following error message when trying to add SProCoP as an external tool:

Warning: unable to access index for repository http://cran.us.r-project.org/bin/windows/contrib/3.0

package 'qcc' is available as a source package but not as a binary

Warning message:
package 'qcc' is not available (for R version 3.0.2)
Warning: unable to access index for repository http://cran.us.r-project.org/bin/windows/contrib/3.0
Warning message:
package 'car' is not available (for R version 3.0.2)

Any help or suggestions on how to fix this would be greatly appreciated.

Thanks,
Linda
