Plot a triangle of comparisons of DEG sets among generations

Plot a triangle of comparisons of DEG sets among generations

Usage

plot_expression_triangle(deg_counts, palette = NULL, box_labels = NULL)

Arguments

deg_counts

Data frame with number of differentially expressed genes per contrast as returned by get_deg_counts.

palette

Character vector of length 4 indicating the colors of the boxes for P1, P2, F1, and midparent, respectively. If NULL, a default color palette will be used.

box_labels

Character vector of length 4 indicating the labels of the boxes for P1, P2, F1, and midparent, respectively. Default: NULL, which will lead to labels "P1", "P2", "F1", and "Midparent", respectively.

Value

A ggplot object with an expression triangle.

Details

The expression triangle plot shows the number of differentially expressed genes (DEGs) for each contrast. Numbers in the center of the lines (in bold) indicate the total number of DEGs, while numbers near boxes indicate the number of up-regulated genes in each generation of the triangle.
