this function provides a list of volume projections in a future age or from one to another future age
project(
firstAge = NaN,
lastAge,
fitDAP,
fitHT,
base,
mapper = list(age1 = "idade1", age2 = "idade2", dap1 = "dap1", dap2 = "dap2", ht1 =
"ht1", ht2 = "ht2"),
calcVolume = calculaVolumeDefault,
withoutBaseFields = F
)
early age. if only one age use NaN
late age for project or the age at which one wants to get the volume
an adjustment of the return type of a function lm() from dap
an adjustment of the return type of a function lm() from ht
a dataset to project
the mapping for the name of the old fields age, dap and ht in base
function to calc volume based base, dap e ht, default calculaVolumeDefault of Fgmutils
want returned projected volume no contains the fields of the base? default no
