  categories = NULL)

Arguments

vals	Input array of values to scale Type: numeric array
varType	Variable type of input array to fillMissing function; affects how scaling occurs. Type: one of following strings: 'character', 'factor', 'logical', 'integer', 'numeric'.
lower	Lower bound for scaling. Type: numeric
upper	Upper bound for scaling. Type: numeric
categories	List of categories. Type: factor

Value

Array of values, either characters, integers, logicals, numerics depending on varType, scaled according to either the number of categories if varType='factor' or 'character', or based on lower and upper when varType='logical','numeric', or 'integer'.
