Usage
"dMax"(low, high, scale = 1, tol = NULL, ...)
"dMin"(low, high, scale = 1, tol = NULL, ...)
"dTarget"(low, target, high, lowScale = 1, highScale = 1, tol = NULL, ...)
"dArb"(x, d, tol = NULL, ...)
"dBox"(low, high, tol = NULL, ...)
"dCategorical"(values, tol = NULL, ...)
"dOverall"(...)
Arguments
low
a constant to define the desirability function for dMax, dMin, dTarget and dBox
high
a constant to define the desirability function for dMax, dMin, dTarget and dBox
target
a constant to define the desirability function for dMax, dMin, dTarget and dBox
scale
the scaling factor for dMax and dMin. Values less than one make the criteria more difficult to satisfy while values greater than one make it easier.
lowScale
the scaling factor for dTarget. This bends the curve between the points low and target. Values less than one make the criteria more difficult to satisfy while values greater than one make it easier.
highScale
the scaling factor for dTarget. This bends the curve between the points high and target. Values less than one make the criteria more difficult to satisfy while values greater than one make it easier.
d
a set of desirabilites between zero and one (inclusive) that match the length of x
values
a named numeric vector of possible values
tol
an optional tolerance for zero desirability. When this is non-null, zero desirabilites are replaced with this value
...
For dOverall, this is one or more desirability objects. For the other methods, this argument is not currently used
