r-cran-transformr - 0.1.4-1 main

In order to smoothly animate the transformation of polygons and
paths, many aspects needs to be taken into account, such as differing number
of control points, changing center of rotation, etc. The 'transformr'
package provides an extensive framework for manipulating the shapes of
polygons and paths and can be seen as the spatial brother to the 'tweenr'
package.
