plotMassDriftG: plotMassDriftG.

In prafols/rMSIproc: MSI Processing in C++

Description

Plot the mass shift observed at a target mass.

Usage

plotMassDriftG(
  peakMatrix,
  peakList,
  target_mass,
  error_range_ppm,
  min_SNR = 10,
  mass_offset = 0,
  title_label = "",
  normalization = NA,
  visible_legend = T,
  legend_title = "",
  N = 1
)

Arguments

peakMatrix	an rMSIproc peak matrix.
peakList	an rMSIproc peak list (no binning here!).
target_mass	the target mass to represent.
error_range_ppm	an error range in ppm to be represented around the target mass.
min_SNR	the minimum signal to noise ratio to be represented.
mass_offset	a mass offset to shift the plot mass axis relative to the target mass.
title_label	a string to be used as plot title. Chemical forumlas will be parsed to produce better results.
normalization	a vector containing the normalization value for each pixel or NA if no normalization should be applied.
visible_legend	a boolean specfing if a legend detailing the included MS images must be displayed.
legend_title	the title for the legend.
N	numbe of dots to display for each pixel, only the N highest SNR will be displayed.

Value

a ggplot2 object.
