Creates a heatmap of pairwise sample correlations, calculated via the Spearman method. The function includes a "smart sorting" feature to correctly order axes based on numeric parts of labels (e.g., "Day1", "Day2", "Day10").

Usage

plot_correlation_heatmap(object, order_by = NULL, label_by = NULL)

Arguments

object: A SummarizedExperiment object.
order_by: Optional. A character string specifying a column in the condition slot by which to order the samples on the heatmap axes. If the column contains numeric parts, a natural sort is applied.
label_by: Optional. A character string specifying a column in the condition slot to use for relabeling the heatmap axes.

Value

A ggplot object representing the heatmap.
