bm_repeat: Mapper for repeating a mapper

In inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Mapper for repeating a mapper

Description

Defines a repeated-space mapper that sums the contributions for each copy. The ibm_n() method returns ibm_n(mapper) * n_rep, and ibm_values() returns seq_len(ibm_n(mapper)).

Usage

bm_repeat(mapper, n_rep, interleaved = FALSE)

bru_mapper_repeat(...)

Arguments

mapper	The mapper to be repeated.
n_rep	The number of times to repeat the mapper. If a vector, the non-interleaved repeats are combined into a single repeat mapping, and combined with interleaved repeats via a bm_sum() of mappers.
interleaved	logical; if TRUE, the repeated mapping columns are interleaved; ⁠(x1[1], x2[1], ..., x1[2], x2[2], ...)⁠. If FALSE (default), the repeated mapping columns are contiguous, ⁠(x1[1], x1[2], ..., x2[1], x2[2], ...)⁠, and the Jacobian is a cbind() of the Jacobians of the repeated mappers. If n_rep is a vector, interleaved should either be a single logical, or a vector of the same length. Each element applies to the corresponding n_rep repetition specification.
...	Arguments passed on to bm_scale()

Value

A bm_repeat or bm_sum object, or the original input mapper.
