plot_feature_overall_stability_incremental | R Documentation |
Perform an incremental ECS between two consecutive feature steps. The ECS values are extracted for every resolution value and summarized using a function (e.g. median, mean, etc.).

feature_object_list,
summary_function = stats::median,
dodge_width = 0.7,
text_size = 4,
boxplot_width = 0.4,
return_df = FALSE
)
feature_object_list |
An object or a concatenation of objects returned
by the |
summary_function |
The function used to summarize the ECS values.
Default is |
dodge_width |
Used for adjusting the horizontal position of the boxplot;
the value will be passed to the |
text_size |
The size of the labels above boxplots. |
boxplot_width |
Used for adjusting the width of the boxplots; the value
will be passed to the |
return_df |
If TRUE, the function will return the ECS values as
a dataframe. Default is |
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.
