rxode2ll 2.0.15

• Fix signed integer overflow: loop indices in llikXxxInternal() Rcpp functions changed from int to R_xlen_t; previously vectors longer than ~500 million elements (>4 GB) could cause undefined behavior due to int overflow when assigned from x.size().
• Fix undefined behavior from unchecked double-to-int casts for discrete distribution count arguments (x, size) exceeding INT_MAX (2147483647); the five affected C-API functions (rxLlikPois, rxLlikBinom, rxLlikGeom, rxLlikNbinom, rxLlikNbinomMu) now return NA instead of invoking undefined behavior for out-of-range inputs.
• Fix type correctness for loop indices in Stan autodiff functor operator() methods across all 15 distributions: changed from int to Eigen::Index to match the return type of Eigen::VectorXd::size().
• Add comprehensive derivative validation tests using central finite differences for all 14 differentiable distributions.
• Add integer overflow bounds-checking tests for all 5 discrete distributions, calling the *Internal() C++ functions directly to bypass R-level input validation.
• Add a skip()-guarded large-vector test that documents the R_xlen_t fix and can be run manually on systems with >4 GB free RAM.
• Changed _log() to _lpmf()/_lpdf() because these functions changed in StanHeaders

rxode2ll 2.0.14

• Make all distribution calculations thread safe

rxode2ll 2.0.13

• Update compile flags in anticipation of BH 1.87.0 (#10)

rxode2ll 2.0.12

• Update compile flags for alpine linux (#7)

rxode2ll 2.0.11

• Update compile flags based on CRAN C++17 requirement (Issue #5)

rxode2ll 2.0.10

• Update compile flags based on StanHeaders change.

rxode2ll 2.0.9

• Initial release, exports log-likelihood functions from ‘stan’ and their derivatives to R and C. This allows linkage in ‘rxode2’ to allow generalized log-likelihood in ‘nlmixr2’.
• This is a data like package and is likely not to change very much over time.
• Added a NEWS.md file to track changes to the package.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
