I ran into a similar problem and wrote a basic package that uses force field
simulation to adjust object location. While much improvement is possible,
including integration with ggplot, etc. it seems to get the task
accomplished. The following illustrates the functionality. If someone runs
into the issue and searches for an answer, hopefully this will be of some
assistance:
install.packages("FField")
library(FField)
FFieldPtRepDemo()
