Dear R-Help-Team, I tried to use isoMDS-Function of the MASS-Package: Message: Fehler: konnte Funktion "isoMDS" nicht finden (error: could not find function "isoMDS")
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. HTH G

ok, MASS seems to be already installed. But I cannot run its functions and I cannot find the path:
.libPaths(MASS)
Fehler in path.expand(new) : objekt "MASS" nicht gefunden What can I do? Thanks in advance Kim
