get_weight: Get weight

In pmcharrison/ppm: Prediction by Partial Matching

Description

Gets the weight (or count) of a given n-gram in a trained PPM moel.

Usage

get_weight(
  model,
  n_gram,
  pos = 1L,
  time = 0,
  update_excluded = FALSE,
  zero_indexed = FALSE
)

Arguments

model	A PPM model object as produced by (for example) new_ppm_simple or new_ppm_decay.
n_gram	An integerish vector defining the n-gram to be queried.
pos	(Integerish scalar) The nominal 'position' at which the n-gram is retrieved (only relevant for decay-based models).
time	(Numeric scalar) The nominal 'time' at which the n-gram is retrieved (only relevant for decay-based models).
update_excluded	(Logical scalar) Whether to retrieve update-excluded counts or not.
zero_indexed	(Logical scalar) Whether the input n-gram is zero-indexed.

Value

A numeric scalar identifying the weight of the n-gram.
