plot_ms {gcxgclab}

Plots the mass spectra of a peak.

Description

plot_ms Plots the mass spectra of a peak.

Usage

plot_ms(ms, title = "Mass Spectrum")

Arguments

ms

a data.frame object. A data frame of the mass values and the percent intensity values, ideally the output of find_ms().

title

a string object. Title placed at the top of the plot. Default title "Mass Spectrum".

Details

This function produces a line plot of the mass spectra data. The mass values vs the percent intensity values as a percent of the highest intensity using ggplot from ggplot2 package (Wickham 2016).

Value

A ggplot object. A line plot of the mass spectra data. The mass values vs the percent intensity values as a percent of the highest intensity.
