Plot chromatograms as heatmap

Source: R/plot_chroms.R
plot_chroms_heatmap.Rd

Plots the specified traces from a list of chromatograms as a heatmap.

Usage

plot_chroms_heatmap(
  chrom_list,
  idx = NULL,
  lambdas,
  engine = c("base", "ggplot", "plotly"),
  show_legend = TRUE,
  xlim = NULL,
  legend_position = "topright",
  title = "",
  show_ylabs = FALSE
)

Arguments

chrom_list

List of chromatograms to plot

idx

A vector representing the names or numerical indices of the chromatograms to plot.

lambdas

A character or numeric vector specifying the wavelengths to plot.

engine

Plotting engine. Either base (matplot), plotly, or ggplot.

show_legend

Logical. Whether to display legend or not. Defaults to TRUE.

xlim

Range of x axis.

legend_position

Position of legend.

title

Title for plot.

show_ylabs

Logical. Whether to show y labels. Defaults to FALSE.

Value

No return value, called for side effects.

Details

Adapted from plot.VPdtw.

Side effects

Plots the traces of the specified chromatograms idx at the specified wavelengths lambdas as a heatmap. Plots can be produced using base graphics engine, ggplot2, or plotly, according to the value of engine.
