Partial Project Through a Composed Partial Projector

Applies partial_project() through each projector in the composition. If colind is a single vector, it applies to the first projector only. Subsequent projectors apply full columns. If colind is a list, each element specifies the colind for the corresponding projector in the chain.

Usage

# S3 method for class 'composed_partial_projector'
partial_project(x, new_data, colind = NULL, ...)

Arguments

x

A composed_partial_projector object.

new_data

The input data matrix or vector.

colind

A numeric vector or a list of numeric vectors/NULLs. If a single vector, applies to the first projector only. If a list, its length should ideally match the number of projectors. colind[[i]] specifies the column indices (relative to the input of stage i) to use for the partial projection at stage i. A NULL entry means use full projection for that stage. If the list is shorter than the number of stages, NULL (full projection) is assumed for remaining stages. If a single numeric vector is provided, it is treated as list(colind, NULL, NULL, ...) for backward compatibility (partial only at first stage).

...

Additional arguments passed to partial_project() or project() methods.

Value

The partially projected data after all projectors are applied.
