Hi,
try with the package cluster!
Bye
Vito
Hello,
I'm trying to do a cluster analysis on a
large data set. I
tried it out with a smaller one first, but I got this
error:
> hc<-hclust(dist(x),"ave")
Error: cannot allocate vector of size 4129151 Kb
The data sample used (i.e. "x")
Thanks folks,
That's exactly what I needed.
Thanks for the speedy replies.
Regards
Wayne

Hi there fellow R-users,
I'm stuck on this seemingly trivial problem.
All I want to coerce a character string into a command.
For example:
x<-rnorm(20)
y<-rnorm(20)
str<-"lm(y~x)"
I want to evaluate the "str" command.
I have tried
eval(as.
Hi there fellow R-users,
I'm stuck on this seemingly trivial problem.
All I want to coerce a character string into a command.
For example:
x<-rnorm(20)
y<-rnorm(20)
str<-"lm(y~x)"
I want to evaluate the "str" command.
I have tried
eval(as.expression(str))
But it doesn't seem to work.
