In brandonsie/bms: Brandon Sie's Personal R Package

Input jpg heatmap, color scale, table dimensions. Output matrix of corresponding values.

Description

Input jpg heatmap, color scale, table dimensions. Output matrix of corresponding values.

Usage

heatmapExtract(
  heatmap,
  scale,
  scale_range = c(1, 0),
  scale_direction = "vertical",
  table_dim,
  n_samples = 1,
  verbose = TRUE
)

Arguments

heatmap	Either image array or path to cropped jpg containing heatmap color info
scale	Either image array or path to cropped jpg containing color scale info
scale_range	Numeric vector of length two containing in order the topmost and bottommost (or leftmost and rightmost) value in the color scale.
scale_direction	Character vector, "vertical" or "horizontal" describing color scale orientation.
table_dim	Numeric vector of length two containing in order the number of rows and number of columns in the heatmap image
n_samples	Number of pixels to sample per cell. By default, heatmapExtract estimates the central pixel of each cell based on the heatmap pixel dimensions and table_dim. If n_samples is set > 1, then heatmapExtract will average across multiple near-central pixels.
verbose	Logical, if true then debugging information will be printed.
