Heatmap of Correlation Differences Between Two Datasets — correlation_diff

Renders the output of correlation_diff as a heatmap (variable by variable), using the same visual language as pca_loading_diff_heatmap: a diverging fill scale centered at zero, so variable pairs with little change are white and larger correlation changes in either direction stand out in Temple Night Owl or cherry.

Usage

correlation_diff_heatmap(
  baseline_data,
  comparison_data,
  cor.use = "everything",
  cor.method = "pearson",
  na_omit = TRUE
)

Arguments

baseline_data: A data frame or tibble treated as the reference.
comparison_data: A data frame or tibble to compare against baseline_data.
cor.use, cor.method, na_omit: See correlation_plot.

Value

A ggplot object.

Examples

set.seed(1)
baseline <- mtcars
comparison <- mtcars[sample(nrow(mtcars), replace = TRUE), ]
correlation_diff_heatmap(baseline, comparison)
