label_meta_clusters: Assign meta cluster labels to rows of a solutions data frame...

In metasnf: Meta Clustering with Similarity Network Fusion

Assign meta cluster labels to rows of a solutions data frame or extended solutions data frame

Description

Given a solutions data frame or extended solutions data frame class object and a numeric vector indicating which rows correspond to which meta clusters, assigns meta clustering information to the "meta_clusters" attribute of the data frame.

Usage

label_meta_clusters(sol_df, split_vector, order = NULL)

Arguments

sol_df	A solutions data frame or extended solutions data frame to assign meta clusters to.
split_vector	A numeric vector indicating which rows of sol_df should be the split points for meta cluster labeling.
order	An optional numeric vector indicating how the solutions data frame should be reordered prior to meta cluster labeling. This vector can be obtained by running get_matrix_order() on an ARI matrix, which itself can be obtained by calling calc_aris() on a solutions data frame.

Value

A solutions data frame with a populated "meta_clusters" attribute.

Examples

#dl <- data_list(
#    list(cort_sa, "cortical_surface_area", "neuroimaging", "continuous"),
#    list(subc_v, "subcortical_volume", "neuroimaging", "continuous"),
#    list(income, "household_income", "demographics", "continuous"),
#    list(pubertal, "pubertal_status", "demographics", "continuous"),
#    uid = "unique_id"
#)
#
#set.seed(42)
#my_sc <- snf_config(
#    dl = dl,
#    n_solutions = 20,
#    min_k = 20,
#    max_k = 50
#)
#
#sol_df <- batch_snf(dl, my_sc)
#
#sol_df
#
#sol_aris <- calc_aris(sol_df)
#
#meta_cluster_order <- get_matrix_order(sol_aris)
#
## `split_vec` found by iteratively plotting ari_hm or by ?shiny_annotator()
#split_vec <- c(6, 10, 16)
#ari_hm <- meta_cluster_heatmap(
#    sol_aris,
#    order = meta_cluster_order,
#    split_vector = split_vec
#)
#
#mc_sol_df <- label_meta_clusters(
#    sol_df,
#    order = meta_cluster_order,
#    split_vector = split_vec
#)
