Hello,
I am trying to use cluster.overplot from package plotrix and I get an error message when
I add the "away" parameter:
require(plotrix)
distance<- read.table("distance.txt")
cmd<- cmdscale(distance)
cp<- cluster.overplot(cmd, away=2)
Error in if (sum(overplots)> 1) { :
missing value where TRUE/FALSE needed
If I don't use "away", everything works fine.
I don't see anything in the documentation that explains this error.
Any help will be appreciated.
Hi Jean,
The "away" argument needs to have both an x and y distance to offset the
points. Try:
cp<-cluster.overplot(cmd,away=c(2,2))
I'll add this to the docs, thanks.
Jim
