abstract: 'Ships statistical and mathematical routines from R internal ''nmath'' (''Mathlib'')
  as ''OpenCL'' C sources under directory ''inst/cl/'', with R wrappers that use the
  GPU when ''OpenCL'' is available at compile time and fall back to ''stats'' equivalents
  otherwise. Aimed at package developers building custom kernels (for example Bayesian
  GLMs via suggested package ''glmbayes'') using ''opencltools'' kernel loaders and
  related helpers. Contains translated shims, an illustrative GLM-related kernel subsystem,
  vignettes, and optional GPU acceleration. The ported routines are translated from
  the ''nmath'' (''Mathlib'') and ''Rmath'' sources of R Core Team (2026) "R: A Language
  and Environment for Statistical Computing" <https://doi.org/10.32614/R.manuals>.
  ''OpenCL'' GPU execution follows the standard described in Stone, Gohara, and Shi
  (2010) <https://doi.org/10.1109/MCSE.2010.69>. The likelihood subgradient simulation
  methodology implemented by the illustrative GLM kernel subsystem is described in
  Nygren and Nygren (2006) <https://doi.org/10.1198/016214506000000357>.'
