Use mrss.to.mdes() to convert an object returned from MRSS functions into an object returned from MDES functions, mrss.to.power() to convert an object returned from MRSS functions into an object returned from power functions, power.to.mdes() to convert an object returned from power functions into an object returned from MDES functions, mdes.to.power() to convert an object returned from MDES functions into an object returned from power functions, and mdes.to.pctl() to convert effect sizes or an object returned from MDES functions into percentiles.
