Generate mz-rt Plot for mass_dataset Object

This function generates a plot of mass-to-charge ratio (m/z) against retention time (rt) for a mass_dataset object. The plot can be either a hexbin plot or a scatter plot based on the hex parameter.

show_mz_rt_plot(object, hex = FALSE)

Arguments

A mass_dataset object for which the mz-rt plot is to be generated.
