Hello,
I am not at all sure that the following answers the question.
The code below ries to find the optimal number of clusters. One of the
changes I have made to your call to kmeans is to subset DMs not dropping
the dim attribute.
library(cluster)
max_clust <- 10
wss <- numeric(max_clust)
Hi Subhamitra,
I think the fact that you are passing a vector of values rather than a
matrix is part of the problem. As you have only one value for each
country, The points plotted will be the index on the x-axis and the
value for each country on the y-axis. Passing a value for ylim= means
that you
2 matches
