Problem installing MASS-Package - R-help

Tue, Feb 10, 2009 1:22 AM #

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")

so I tried to install the package MASS:

versuche URL 'http://cran.rakanu.com/bin/windows/contrib/2.8/VR_7.2-45.zip'
Content type 'application/zip' length 1598763 bytes (1.5 Mb)
URL ge?ffnet
downloaded 1.5 Mb

Bundel 'VR' erfolgreich ausgepackt und MD5 Summen abgeglichen
Warnung: kann alte Installation von Paket 'MASS' nicht entfernen

Die heruntergeladenen Pakete sind in 
        C:\Dokumente und Einstellungen\kvanselow\Lokale Einstellungen\Temp\RtmpeIMdIP\downloaded_packages
aktualisiere HTML Paketbeschreibungen

ok, MASS seems to be already installed. But I cannot run its functions and I cannot find the path:

Fehler in path.expand(new) : objekt "MASS" nicht gefunden

What can I do?
Thanks in advance

Kim

Did you load the package from your library first, e.g.:

library(MASS)
isoMDS(....)

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.

Hi

Did you try to issue

library(MASS)

before calling isoMDS?

Regards
Petr
