Did you load the package from your library first, e.g.: library(MASS) isoMDS(....) > > so I tried to install the package MASS: MASS is part of recommended package bundle VR and as such, should come with every version of R on all binaries for the different OSes (IIRC), you shouldn't need to install it. Your .libPaths(...) call raised an error because you didn't provide a character vector for the path to a library location. .libPaths() is not designed to do what you appeared to think it did - it deals with setting/getting paths to where packages are located. Reading section 13 of the manual "An Introduction to R" would have explained all of this.
