degree {dials} | R Documentation |
These parameters help model cases where an exponent is of interest (e.g.
degree()
or spline_degree()
) or a product is used (e.g. prod_degree
).
degree(range = c(1, 3), trans = NULL)
degree_int(range = c(1L, 3L), trans = NULL)
spline_degree(range = c(1L, 10L), trans = NULL)
prod_degree(range = c(1L, 2L), trans = NULL)
range |
A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units. |

degree()
is helpful for parameters that are real number exponents (e.g.
x^degree
) whereas degree_int()
is for cases where the exponent should be
an integer.
The difference between degree_int()
and spline_degree()
is the default ranges
(which is based on the context of how/where they are used).
prod_degree()
is used by parsnip::mars()
for the number of terms in
interactions (and generates an integer).
