[R] summing values as image

I'm trying to summarize irregularly spaced data (in data.frame with x,y,z) and need to sum (not average as the as.image() function in fields does) and I'm not sure if there is a function in on of the packages or if I'm going to need to string a few functions together like fields::as.image() and fields::image.count() to get what I need or if I should simply write my own.

suggestions?
