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.
