ibm_is_rowwise: Check if a mapper is rowwise

In inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Check if a mapper is rowwise

Description

Implementations must return TRUE or FALSE. If TRUE (returned by the default method unless the mapper contains an is_rowwise variable), users of the mapper may assume the mapper uses its inputs in "rowwise" manner, so that blockwise evaluation is always possible.

Usage

ibm_is_rowwise(mapper, ...)

## Default S3 method:
ibm_is_rowwise(mapper, ...)

Arguments

mapper	A mapper S3 object, inheriting from bru_mapper.
...	Arguments passed on to other methods

Value

logical; TRUE if the mapper is rowwise, FALSE otherwise.

Methods (by class)

• ibm_is_rowwise(default): Returns logical is_rowwise from the mapper object if it exists, and otherwise TRUE.

m <- bm_linear()
