`rtrange` | numeric vector of length >= 2 whose range will be used to select the retention times to plot
`scanrange` | numeric vector of length >= 2 whose range will be used to select scans to plot
`log` | logical, log transform intensity
`title` | main title of the plot

### Value

A matrix with the points plotted.
