Add a column that tells us which "missingness cluster" a row belongs to

A way to extract the cluster of missingness that a group belongs to. For example, if you use vis_miss(airquality, cluster = TRUE), you can see some clustering in the data, but you do not have a way to identify the cluster. Future work will incorporate the seriation package to allow for better control over the clustering from the user.

add_miss_cluster(data, cluster_method = "mcquitty", n_clusters = 2)

Arguments

data

a dataframe

cluster_method

character vector of the agglomeration method to use, the default is "mcquitty". Options are taken from stats::hclust helpfile, and options include: "ward.D", "ward.D2", "single", "complete", "average" (= UPGMA), "mcquitty" (= WPGMA), "median" (= WPGMC) or "centroid" (= UPGMC).

n_clusters

numeric the number of clusters you expect. Defaults to 2.
