Internal utilities for native calls and helpers

Source: R/internal-utils.R
internal_utils.Rd

Lightweight wrappers for calling into the C++ backend plus helper utilities reused throughout the package.

Usage

.call(fn_name, ...)

.expand(...)

.set_dim(x, dim)

.polygonize(x)

.rast_tmpl(x)

.modify_list(x, y)

Functions

  • .call(fn_name, ...) Executes the registered C++ symbol via .Call and wraps errors with friendly messages.

  • .expand(...) A thin wrapper around expand.grid() that drops row attributes and prevents factor coercion.

  • .set_dim(x, dim) Re-shapes x by delegating to the snic_set_dim native routine.

  • .polygonize(x) Converts a segmentation raster into polygons.

  • .rast_tmpl(x) Builds an empty terra::rast() template matching the array's footprint.

  • .modify_list(x, y) Modifies x list using named entries from y
