hi,
when I use bclust in R, bclust(dat,centers=5,minsize=3,base.centers=4)
dat has 25 rows, there is an error as following:
Error in knn1(object$allcenters, x, factor(1:nrow(object$allcenters))) :
train and class have different lengths
when I debug this function , I found the error is in the prune.bclust function.
But I can not search the help doc of this function.
which package is this function in?
Meanwhile I think there is a bug in blcust: bclust(x, centers=2,
iter.base=10, minsize=0,
dist.method="euclidian",
hclust.method="average", base.method="kmeans",
base.centers=20, verbose=TRUE,
final.kmeans=FALSE, docmdscale=FALSE,
resample=TRUE, weights=NULL, maxcluster=base.centers, ...)
if the centers is larger than base.centers, maxcluster is default,ie is equal to
base.centers, then it will occur an error as following:
Error in clusters.bclust(object, centers) : subscript out of bounds
because this line object$members <- cutree(object$hclust, 2:maxcluster) in
hclust.bclust function denotes that object$members has (maxcluster-1) columns,
it will occur subscript out of bounds.
I think the maxcluster may be setted as max(base.centers, centers), is it right?
Thanks you very much!>
