| slicing {denpro} | R Documentation |
Returns a one- or two-dimensional slice of a multivariate function. The functions are represented as piecewise constant functions.
slicing(pcf, vecci, d1 = 1, d2 = NULL)
pcf |
a piecewise cosntant function |
vecci |
vector inside the support of the function which fixes the variables; length of "vecci" is d-2 or d-1, depending on whether the slice is 2- or 1-dimensional |
d1 |
integer 1,...,d; the first variable of the slice |
d2 |
integer 1,...,d, not equal to d1; the second variable of the slice |
a piecewise constant function
