## Identifying mutational clusters in 3D protein space using simulation.

### Description

The SpacePAC package identifies non-random amino acid clusters in proteins in 3D space and is a sister package to iPAC and GraphPAC. SpacePAC considers 1, 2 or 3 non-overlapping spheres with radii specified by the user and through simulation, attempts to identify spheres where there are more mutations than expected by random chance alone. These results are then outputted in the form of a list with p-values.

### Details

Please see `get.Positions` and `get.AlignedPositions` in the iPAC package for information about obtaining positional data.
