Hello,
I'm trying to draw a simplified tree of a cluster object
with maptree, but I get an error message:
> class(vars.agn)
[1] "agnes" "twins"
> draw.clust (clip.clust (vars.agn, k=5))
Error in "names<-.default"(`*tmp*`, value = c("merge",
"height", "order",'names' attribute [8] must be the
same
length as the vector [7]
Trying converting first to object of class "hclust":
> draw.clust (clip.clust (as.hclust(vars.agn), k=5))
Error in split(x, f) : first argument must be a vector
But conversion seems to work fine:
> vars.hclust=as.hclust(vars.agn)
> vars.hclust
Call:
agnes(x = daisy(vars.cluster), diss = TRUE, method =
"ward")
Cluster method : ward
Number of objects: 295
> draw.clust (clip.clust (vars.hclust, k=5))
Error in split(x, f) : first argument must be a vector
A previous version of maptree successfully clipped the
three from the same data. Any orientation will be greatly
appreciated.
Thank you in advance.
