Text hashing parameters — num

Used in textrecipes::step_texthash() and textrecipes::step_dummy_hash().

Usage

num_hash(range = c(8L, 12L), trans = transform_log2())

signed_hash(values = c(TRUE, FALSE))

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.
values: A vector of possible values (TRUE or FALSE).

Examples

num_hash()
#> # Hash Features (quantitative)
#> Transformer: log-2 [1e-100, Inf]
#> Range (transformed scale): [8, 12]
signed_hash()
#> Signed Hash Value (qualitative)
#> 2 possible values include:
#> TRUE and FALSE
