                        Changes in version 0.2.0                        

Major changes

This is the first release as a complete R package, and the version that
has undergone open review with rOpenSci. The main features of
tacmagic 0.2.0 are implemented and tested: loading PET time activity
curve (tac) data from multiple formats, merging ROIs weighted for
volume, calculating binding potential models including SUVR and DVR,
basic plotting, and calculation of cut-off values. As tacmagic is still
a new package and testing to date is based on few example files, it is
essential to verify that all functions are behaving as expected when
applied to your own data.
