Make a Heatmap for a Grid

Description

The function makes a heatmap showing cell counts for a grid. By default, darker colours indicate larger counts, while lighter colours indicate smaller counts.

Usage

make_heatmap(
  grid,
  labels = c("agree_disagree", "satisfied_dissatisfied", "positive_negative",
    "accurate_inaccurate", "other"),
  title = "Heatmap for Grid Item",
  pos_labels = NULL,
  neg_labels = NULL,
  colours = c("purple", "green", "red", "custom"),
  custom_palette,
  show_counts = TRUE,
  breaks = NA,
  fontsize = 20,
  fontsize_names = 11
)

Arguments

`grid`	a matrix.
`labels`	a character string specifying which set of row names and col names are to be used.
`title`	the title of the plot.
`pos_labels`	character. Custom column names.
`neg_labels`	character. Custom row names.
`colours`	a character string indicating what colour the heatmap will be. Choosing `"custom"` allows for setting the `custom_palette` variable to a palette other than `"purple"`, `"green"`, or `"red"`.
`custom_palette`	a colour palette, the output of `colorRampPalette`.
`show_counts`	logical. If `TRUE`, counts are shown for each cell.
`breaks`	A sequence of numbers that covers the range of values in the grid. If the value is `NA`, the breaks are calculated automatically.
`fontsize`	base fontsize for the heatmap.
`fontsize_names`	fontsize for row and column names.
