ggcorrheatmap (development version)

CRAN release: 2025-10-05

The new split_diag argument allows for triangular cells in the diagonal.
Square matrices where the row- and column names are the same now work with features that previously required a symmetric matrix (such as triangular layouts).

return_data now always returns a layout column.
The legends in ggcorrhm() no longer assume that Pearson correlation was used when cor_in is TRUE.

show_names_x/y and names_x/y_side have been deprecated in favour of show_names_cols/rows and names_cols/rows_side for consistency with other arguments.

CRAN release: 2025-08-24

The scale-modifying arguments bins, limits, high, mid, low, and size_range can now take two inputs in mixed layouts.
The new scale_data argument allows for scaling rows or columns.
The new gghm_tidy() and ggcorrhm_tidy() functions can make heatmaps from long format data using tidy input.
The new cor_long() function makes it convenient to calculate correlations from long format data.
The new add_mixed_layout() function can add mixed layout labels to long format data to aid in cell label creation.
The new split_rows and split_cols arguments can be used to add gaps to the heatmap via facets.

The new annot_rows_names_params and annot_cols_names_params arguments (that provide parameters to ggplot2::geom_text()) supersede annot_rows_name_params and annot_cols_name_params that don’t work with heatmap splits.

The default continuous colour scale nr 7 now works.
The bins argument now only accepts positive numbers and, for non-integer values, values above 3 as other values do not work.
The ‘none’ mode now works with annotation.
