If you use OncoSimulR, please cite the OncoSimulR Bioinformatics paper.
OncoSimulR has been used in three large comparative studies of methods
to infer restrictions in the order of accumulation of mutations (cancer
progression models) published in PLoS Computational Biology,
Bioinformatics and BMC Bioinformatics; you might want to cite those
too, if appropriate, such as when referring to using evolutionary
simulations to assess oncogenetic tree/cancer progression methods
performance.
