I'm referring to line
```
#' Fit a k-means model
#'
#' Fit a k-means model, similarly to R's kmeans().
```
ie. the first line and the third line.
For example, it shows up for `glm` like this
http://spark.apache.org/docs/latest/api/R/glm.html
Which I'd think would be rather odd if they are not consistent.
