[R] Error running sammon() in multiv package

[Kyriakos Kachrimanis]

When I try to run the "sammon" function of the multiv package, I always get
this error message:

Error in as.vector(dist(a)) : couldn't find function "dist"

It happens even with example(sammon). I am running R 1.5.0 on Win98 and I
have still installed R 1.4.1 but it doesn't work on the old R version with
the older multiv package either. Is there a problem with the function or do
I have to install and load some other package also?
In which package is the "dist" function located?

Thank you in advance,
Kyriakos Kachrimanis
