Error in library(xyz) : package 'xyz' is not installed. Nonetheless, Kevin Wright's function is interesting. __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Many beginners are advanced but just don't know R. Its better to give them the information they need. With this they can discover what is there even without knowing the relevant R commands. -- Statistics Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
Re: [Rd] Error message library()
I agree: much nicer to say what went wrong than to say there is no package And many people will not know what R's paths are. Why not add in a hint about what to do, like: try running install.packages(xyz) t ggrothendieck Many beginners are advanced but just don't know R. Its better to give them the information they need. With this they can discover what is there even without knowing the relevant R commands.
