plot_feature_stability_ecs_incremental {ClustAssess}

Feature Stability Incremental Boxplot

Description

Perform an incremental ECS between two consecutive feature steps.

Usage

plot_feature_stability_ecs_incremental(
  feature_object_list,
  dodge_width = 0.7,
  text_size = 4
)

Arguments

feature_object_list

An object or a concatenation of objects returned by the 'get_feature_stability' method.

dodge_width

Used for adjusting the horizontal position of the boxplot; the value will be passed in the 'width' argument of the 'ggplot2::position_dodge' method.

text_size

The size of the labels above boxplots.

Value

A ggplot2 object with ECS distribution will be displayed as a boxplot. Above each boxplot there will be a pair of numbers representing the two steps that are compared.

Examples

set.seed(2021)
# create an artificial expression matrix
expr_matrix = matrix(c(runif(25*10), runif(75*10, min = 5, max = 7)), nrow = 100, byrow = TRUE)
rownames(expr_matrix) = as.character(1:100)
colnames(expr_matrix) = paste("feature", 1:10)

feature_stability_result = get_feature_stability(data_matrix = t(expr_matrix),
   feature_set = colnames(expr_matrix),
   feature_type = "feature_name",
   steps = c(5,10),
   npcs = 2,
   n_repetitions = 3,
