After the previous post on the packcircles package for R someone suggested it would be useful to be able to fix the position of selected circles. As a first attempt, I've added an optional weights argument to the circleLayout function. Weights can be in the range 0-1 inclusive, where a weight of 0 prevents a circle from moving, while a weight of 1 allows full movement. The updated code is at GitHub . Here's an example where the largest of a set of initially overlapping circles is fixed in place: And here is the code for the example: library(packcircles) library(ggplot2) library(gridExtra) # Generate some random overlapping circles ncircles
