Heatmap of clinical association across populations or markers

WHAT IS ON THE TILE. The signed effect where one exists – Spearman's rho, or Cliff's delta – so the colour carries direction as well as strength. A Kruskal-Wallis row has no signed effect and is drawn grey with its p-value, because a three-level variable has no single direction to show.

Usage

fig_clinical_heatmap(
  assoc,
  key_col,
  outfile,
  title = "Clinical association",
  dpi = 200,
  colors = fcs_colors()
)

Arguments

assoc: data frame from clin_associate().
key_col: "population" or "marker".
outfile: path.
title: figure title.
dpi: resolution.
colors: palette.

Details

Significance is marked on the tile rather than encoded in the colour, so a large effect that did not survive correction still reads as large. On a cohort this size that distinction is most of the message.
