Kernel parameters — rbf

Parameters related to the radial basis or other kernel functions.

rbf_sigma(range = c(-10, 0), trans = transform_log10())

scale_factor(range = c(-10, -1), trans = transform_log10())

kernel_offset(range = c(0, 2), trans = NULL)

Arguments

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.
trans: A trans object from the scales package, such as scales::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

Details

degree() can also be used in kernel functions.
