plot_chroms: Plot traces from list of chromatograms.

In ethanbass/chromatographR: Chromatographic Data Analysis Toolset

Plot traces from list of chromatograms.

Description

Plots the specified traces from a list of chromatograms.

Usage

plot_chroms(
  x,
  lambdas,
  idx,
  xlim,
  ylim,
  xlab = "",
  ylab = "Absorbance",
  engine = c("base", "ggplot", "plotly"),
  linewidth = 1,
  show_legend = TRUE,
  legend_position = "topright",
  ...
)

Arguments

x	A list of chromatograms in matrix format (timepoints x wavelengths).
lambdas	The wavelength(s) you wish to plot the trace at.
idx	A vector representing the names or numerical indices of the chromatograms to plot.
xlim	Range of x axis.
ylim	Range of y axis.
xlab	X label.
ylab	Y label. Defaults to "Absorbance".
engine	Plotting engine. Either base (matplot), plotly, or ggplot2-package.
linewidth	Line width.
show_legend	Logical. Whether to display legend or not. Defaults to TRUE.
legend_position	Position of legend.
...	Additional arguments to plotting function specified by engine.

Value

No return value, called for side effects.

Side effects

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