Hi Everyone,

So I am trying to use the clusterboot function in the fpc package in R. Really I want some measures of cluster stability. I would love to get something like p-values on the different branches of the dendrogram.  I've tried to use this function now but I haven't yet been able to. I'm not quite sure what I'm doing wrong. I create a dissimilarity matrix of my data and then run the function with the code below:

dMOFF.2007<-dist(MOFF.2007)
cf1 <- clusterboot(MOFF.2007,B=3,bootmethod=boot,bscompare=TRUE,multipleboot=TRUE,clustermethod=hclust)

I get the error:
Error in if (is.na(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") :
  missing value where TRUE/FALSE needed

I have no idea what this means. Does anyone have any suggestions? Also suggestions on how to use this function in general would be great as well. Any other way to get metrics on the validity of clusters would be great too.

Cheers,
