What information is contained in the object returned by the R kmeans function?
The object returned by the kmeans function contains a cluster assignment for each data point and the coordinate location of the center of each cluster.
Reasoning, step by step
- Run the kmeans function on a dataset.
- Inspect the returned object.
- Identify the clustering vector, which assigns each data point to a cluster.
- Identify the cluster means, which provide the coordinates of each cluster's center.
Example
The speaker explains that the resulting kmeans object contains valuable information, including a cluster assignment for each data point and the coordinate location of each cluster's center.
Common misconceptions
- Thinking the object only contains the final cluster labels.
- Assuming the cluster centers are not included in the output object.
