Hi,
I'm currently using EMA package to make clustering and heatmaps.
The online doc concerning the package gives the following example code:
data(marty)
c<-clustering(marty, metric="pearson", method="ward")
clustering.plot(c, title="Hierarchical Clustering\nPearson-Ward")
which is working perfectly,
However, when I'm changing the method to method="kcentroids", on the exact
same example, I got the following error:
Error in DIS$DIS : $ operator is invalid for atomic vectors
Here is the code ran :
data(marty)
c<-clustering(marty, metric="pearson", method="kcentroids", 4)
clustering.plot(c, title="Hierarchical Clustering\nPearson-Ward")
I even tried to transform the data to a dataframe with the following code :
data(marty)
c<-clustering(data.frame(marty), metric="pearson", method="kcentroids", 4)
clustering.plot(c, title="Hierarchical Clustering\nPearson-Ward")
but it's not working either...
Someone know how I can correct this issue? Or should I use classical
hclust() function instead of clustering() ?
Thanks
