I have loaded a shapefile into r studio and used the plot function to plot the polygons representing different counties.

When I go to label the polygons with ordered numbers 1-28, the label appear but they are stacked in certain areas.

Is there anything I can do to so the number labels aren't stacked?

I've included a copy of my code and screenshot of my plot below.
