Dear R experts,
I have a labeled data set. Each data is assigned a binary label 0 or 1.
Assume that I use some clustering algorithm to group the data by clusters
(using some features of the data). Now I want to know how many data are
labeled as 0/1 in each cluster.
For example, assume that I have 9 labeled data grouped into three clusters.
The ids of the clusters are 1, 2, and 3. The dataset is represented by the
following matrix:
membership Label
d1 1 0
d2 1 0
d3 1 1
d4 2 0
d5 2 1
d6 2 1
d7 3 1
d8 3 1
d9 3 1
Now I want to get the following output, telling me how many data are labeled
as 0 and 1 in each cluster
cluster_id 0-data 1-data
1 2 1
2 1 2
3 0 3
The output does not have to be a matrix, it could be a summary of the
statistics.
How should I approach this problem? What R functions should I use to get
such information?
Thanks so much!
Boya
