Basically, I have the location data for about 1,000 pitches. I can get them
to show up correctly on normal plots, but I am genuinely messed up on
heatmaps.

location <- read.csv('C:/Users/William/Downloads/09Location.csv')
location <- as.matrix(location)

Like I said, that can get a plot fine.

You may think that you attached a file and that we can see it. The first may be true, but the second is FALSE. You probably want a 2D density estimator. Try searching rseek or RSiteSearch for "2d density".



Should I use image or heatmap?
For the record, I want something like
this:http://2.bp.blogspot.com/_hZYdwHvvD9U/THo_YaK0dGI/AAAAAAAAAgg/VjzVngS2-BU/s1600/clifflee3.png

I don't need the contour lines, though.
