Heatmap of missing values — plot_heatmap • MetaboCrates

plot_heatmap() creates a heatmap of missing values for the specified plate bar code or for all of them.

Usage

plot_heatmap(
  dat,
  plate_bar_code = NULL,
  include_title = FALSE,
  show_colors = TRUE
)

dat: a raw_data object. Output of read_data() function.
plate_bar_code: a single plate bar code used to select observations to include in the plot. If NULL (default), a grid of plots is returned, where each plot corresponds to a different plate bar code.
include_title: logical. Indicates whether the title with the plate bar code should be included (only if plate_bar_code is not NULL). Defaults to FALSE.
show_colors: logical. If TRUE, distinct colors are applied to different types of missing values, following the conventions used in Biocrates® files.

path <- get_example_data("small_biocrates_example.xls")
dat <- read_data(path)
plot_heatmap(dat, "1036372116-1 | 1036372121-1")
