  order = NULL,
  cluster_solution = NULL,
  scale_diag = "mean",
  log_graph = TRUE,
  cluster_rows = FALSE,
  cluster_columns = FALSE,

  split_vector = NULL,
  row_split = NULL,
  column_split = NULL,
  ...
)

Arguments

similarity_matrix	A similarity matrix
order	Vector of numbers to reorder the similarity matrix (and data if provided). Overwrites ordering specified by cluster_solution param.
cluster_solution	Row of a solutions data frame or column of a transposed solutions data frame.
scale_diag	Method of rescaling matrix diagonals. Can be "none" (don't change diagonals), "mean" (replace diagonals with average value of off-diagonals), or "zero" (replace diagonals with 0).
log_graph	If TRUE, log transforms the graph.
cluster_rows	Parameter for ComplexHeatmap::Heatmap.
cluster_columns	Parameter for ComplexHeatmap::Heatmap.
show_row_names	Parameter for ComplexHeatmap::Heatmap.
show_column_names	Parameter for ComplexHeatmap::Heatmap.
data	A data frame containing elements requested for annotation.
left_bar	Named list of strings, where the strings are features in df that should be used for a barplot annotation on the left of the plot and the names are the names that will be used to caption the plots and their legends.
right_bar	See left_bar.
top_bar	See left_bar.
bottom_bar	See left_bar.
left_hm	Like left_bar, but with a heatmap annotation instead of a barplot annotation.
right_hm	See left_hm.
top_hm	See left_hm.
bottom_hm	See left_hm.
annotation_colours	Named list of heatmap annotations and their colours.
min_colour	Colour used for the lowest value in the heatmap.
max_colour	Colour used for the highest value in the heatmap.
split_vector	A vector of partition indices.
row_split	Standard parameter of ComplexHeatmap::Heatmap.
column_split	Standard parameter of ComplexHeatmap::Heatmap.
...	Additional parameters passed into ComplexHeatmap::Heatmap.

Value

Returns a heatmap (class "Heatmap" from package ComplexHeatmap) that displays the similarities between observations in the provided matrix.

#    list(
#        data = expression_df,
#        name = "expression_data",
#        domain = "gene_expression",
#        type = "continuous"
#    ),
#    list(
#        data = methylation_df,
#        name = "methylation_data",
#        domain = "gene_methylation",
#        type = "continuous"
#    ),
#    uid = "patient_id"
#)
#
#sc <- snf_config(my_dl, n_solutions = 10)
#
#sol_df <- batch_snf(my_dl, sc, return_sim_mats = TRUE)
#
#sim_mats <- sim_mats_list(sol_df)
#
#similarity_matrix_heatmap(
#    sim_mats[[1]],
#    cluster_solution = sol_df[1, ]
