plotLSV {eChem}

Plot Linear Sweep Voltammograms

Description

Plots 1–5 linear sweep voltammograms on a single set of axes. The default plot does not include a legend or a title, but providing a vector of character strings to legend_text adds a legend to the final plot, and adding a character string for main_title adds a title to the plot. Line widths, line types, line colors, point symbols, and point colors have default values that can be adjusted. Note: this function accepts both full data files created using lsvSim, or reduced data sampleLSV.

Usage

plotLSV(filenames = list(file1 = NULL, file2 = NULL), legend_text = NULL,
  legend_position = c("topleft", "topright", "bottomleft", "bottomright"),
  main_title = NULL, line_widths = c(2, 2, 2, 2, 2), line_types = c(1, 2,
  3, 4, 5), point_symbols = c(21, 22, 23, 24, 25), line_colors = c("blue",
  "blue", "blue", "blue", "blue"))

Arguments

filenames

A list giving the names of 1–5 files that contain the results of a simulated linear sweep voltammetry experiment.

legend_text

Optional vector that contains text to include in a legend. Default is NULL, which surpresses the legend.

legend_position

One of topleft, topright, bottomleft, or bottomright; defaults to topleft.

main_title

An optional main title.

line_widths

A vector of line widths for the individual linear sweep voltammograms; defaults to a common line width of 2, but can be adjusted by supplying a vector with desired values.

line_types

A vector of line types for the individual linear sweep voltammograms; defaults to a set of different line types, but can be adjusted by supplying a vector with desired values.

point_symbols

A vector of pch values for plotting points.

line_colors

A vector of colors for the individual linear sweep voltammograms, whether displayed as lines or as points; defaults to a common color, but can be adjusted by supplying a vector with desired values.

Value

Returns a plot that shows the applied potential on the x-axis and current on the y-axis.

Examples

lsv_ex1 = simulateLSV(e.start = 0.25, e.end = -0.25, e.form = 0,
  stir.rate = "fast", x.units = 100, t.units = 1000)
lsv_ex2 = simulateLSV(e.start = 0.25, e.end = -0.25, e.form = 0,
  stir.rate = "medium", x.units = 100, t.units = 1000)
lsv_ex3 = simulateLSV(e.start = 0.25, e.end = -0.25, e.form = 0,
  stir.rate = "slow", x.units = 100, t.units = 1000)
lsv_ex4 = simulateLSV(e.start = 0.25, e.end = -0.25, e.form = 0,
  stir.rate = "off", x.units = 100, t.units = 1000)
plotLSV(filenames = list(lsv_ex1, lsv_ex2, lsv_ex3, lsv_ex4),
  legend_text = c("stir rate: fast", "stir rate: medium",
  "stir rate: slow", "stir rate: off"))
