I would like to know how to make a plot in R where the y-axis is inverted such that the plotted data appears in what would be the fourth quadrant (IV) of a cartesian plane, as opposed to the first (I) quadrant.

For reference, the plot I am trying to make looks very similar to the following (source):

a plot with inverted y-axis

I have found a number of questions online pertaining to reversing the numbering on the y-axis, but these all still plot the data in the first quadrant. Can anyone suggest how I might produce a plot similar to that shown above?
