Hello,

I have a list of X,Y coordinates and a ratio associated with each

coordinate. The X and Y coordinates are continuous but random from

50-500, I would like to make a continuous heatmap of the ratios at each

coordinate. One caveat is that the coordinates are clustered together

do some bixes might have too little data. I am wondering if there is a

way that R can automatically adjust box sizes? Sample data set is below

TIA

X Y RATIO

50 56 .1

50 59 .1

52 54 .2

500 393 .9

450 36 .7

250 190 .7
