How to find the border points of a particular shape

Pergunta

Suppose I have a irregular, random, shape generated from a dataset. How do I find points that are situated on the shape's border?

I am using R. Are there any packages in R for this purpose? For simplicity, just assume that I have a 2d dataset of points.
