This sorts the data, identifies parameters and function value (response), identifies pairs of response values for identical parameter values, and may set some global controls in blackbox.options().
prepareData(data, ParameterNames=NULL, respName=NULL,
verbose=TRUE)A data frame with the required variables, ordered by increasing values as in do.call(order,data).
This may set some global controls in blackbox.options() as a side effect.
A data frame including variables in ParameterNames and respName
Names of the variables to be used as predictors of the smoothed surface. If NULL, all columns except the last are assumed to hold parameter values.
Name of the variable to be used as response of the smoothed surface. If NULL, the last column is assumed to hold function values.
Whether to print some information (in particular a message if replicate responses values are identical for given parameter values, whichwill be suspect in some applications)
