  calc.file.name = "example.data/calc.cheng.csv", seed = seedVal,
  above.threshold = 0)

bmd.file.name	string. the location of the input file for bmds (al least it has to have 'bmd' and 'id' columns)
efs.file.name	string. table of EFs to be applied (see excel file in inst for instructions)
above.threshold	numeric. If present values less equal to it are discarded from generated bmd distribution

Details

from the BMD values extracts GM and GSD, randomly picks the same amount from the corresponding lognormal distriution, then for each row in the EF table picks the corresponding random values and applies the corresponding operator in cascade
