Add a single point to an online LOESS model

Usage

add_point(model, ...)

# S3 method for class 'OnlineLoess'
add_point(model, x, y, weight = 1, ...)

Arguments

model: An OnlineLoess object.
...: Must be empty.
x: A numeric coordinate vector with one value per configured dimension. For one-dimensional models, a scalar is also accepted.
y: A single numeric y value.
weight: Finite non-negative case weight for this observation; defaults to 1.

Value

An online result list, or NULL if fewer than min_points have been added.

Examples

model <- OnlineLoess(fraction = 0.2, window_capacity = 20L, min_points = 2L)
invisible(add_point(model, 1.0, 0.5))
add_point(model, 2.0, 0.6)
