tgstat 2.4.0

• Added tgs_chi2(): vectorized chi-squared test for 2x2 contingency tables with optional Yates' continuity correction. Supports both dense and sparse (dgCMatrix) matrix input. Useful for differential gene expression analysis. C++ backend with fork-based parallelization for large matrices and erfc(sqrt(x/2)) optimization for p-value computation.

tgstat 2.3.32 (2026-03-20)

• Replaced non-API C entry point Rf_findVar with R_getVar for R 4.6.0 compatibility.
• Added .claude to .Rbuildignore.

tgstat 2.3.30

• FIFO temp directory is now configurable via options(tgs_tmpdir = "/path") or the TMPDIR environment variable, instead of being hardcoded to /tmp. Fixes permission errors on systems where /tmp is restricted (#17).
• Added a child-process liveness check in wait_for_kid()/wait_for_kids() to prevent potential hangs when child processes terminate unexpectedly without being reaped (#18).
• Added comprehensive tests for tgs_cor_knn and temp directory configuration.
