text2map

• warnings across the package now use cli::cli_warn(), matching existing cli::cli_abort()/cli::cli_inform() usage
• all stop() calls across the package now use cli::cli_abort() for consistent, better-formatted error messages (error text is unchanged where tests depend on specific wording)
• doc_centrality() and dtm_stats() now warn on degenerate input (documents with no ties; empty DTMs) instead of silently returning NaN
• consolidated the four .terms_stop_* internal helpers (dtm_stopper()'s term/document frequency and proportion rules) into one shared .terms_stop_filter(), removing ~100 lines of duplicated Inf-replacement/rounding/threshold logic; no behavior change
• dtm_builder()'s friendly error messages (empty last row; missing doc ID column) are now raised as a single error with the original Matrix/dplyr error preserved as the cause, instead of a separate message() immediately followed by the raw error
• CoCA() now warns (previously just informed) when it overrides an explicit filter_sig = TRUE because too few directions were supplied
• added RhpcBLASctl as an Import and pinned BLAS/OpenMP to a single thread around every text2vec::RWMD call (CMDist(), doc_similarity(method = "wmd")); text2vec's compiled Word Mover's Distance code can deadlock under a multi-threaded BLAS (e.g. OpenBLAS) due to nested OpenMP thread-pool contention, and this can't be worked around with an environment variable set at runtime since the thread pool is already initialized by the time any R code runs

Corrections

• fixed empty dtm_stats test by adding missing assertions
• fixed dfm cbind warning: early-return now only for pure dgCMatrix, not subclasses like dfm
• suppress plot windows in tests with pdf(NULL)
• fixed RNG state leaking into the caller's session in rancor_builder()/rancors_builder() when seed = NULL
• fixed .Random.seed not found errors in a fresh R session in perm_tester(), test_anchors() (relco method), and plot.CoCA()
• fixed doc_centrality(method = "span") incorrectly requiring igraph
• fixed perm_tester() crashing with object 'x' not found when the model has exactly 2 coefficients (missing drop = FALSE in column subset)
• fixed find_transformation(method = "align") crashing with non-conformable arguments when wv/ref have different row counts (now validates upfront)
• fixed dtm_builder() producing a DTM with the wrong number of rows when the last document had zero tokens (Matrix::sparseMatrix() inferred nrow from max(i) instead of actual document count; now passes explicit dims)
• registered relco print methods (tbl_sum.relco, tbl_format_footer.relco) as S3 methods; previously silently unused
• fixed plot.CoCA() crashing with an unhelpful error on invalid/out-of-range module
• fixed dtm_builder(vocab =, chunk =) creating a spurious extra chunk row at exact chunk-size boundaries, and silently dropping (instead of bucketing) out-of-vocabulary tokens
• fixed .dtm_error_handler() no longer recognizing current Matrix package error wording
• fixed wrong argument name in dtm_stopper(stop_termprop =)'s error message
• fixed CMDist() crashing on single-document DTMs
• fixed get_direction(method = "PCA") giving an unrelated error when n_dirs exceeds available anchor pairs
• fixed get_direction()'s \examples calling method = "PCA" with only one anchor pair, which failed R CMD check after the two-pair minimum above was added
• added .ontomics (a local tool directory, not part of the package) to .Rbuildignore; was triggering an R CMD check NOTE
• fixed find_transformation(method = "retrofit") giving an opaque error when wv/ref share no vocabulary
• fixed perm_tester() giving an opaque error for an invalid statistic argument
• fixed get_centroid()/get_direction() silently corrupting results when missing = "remove" dropped an out-of-vocabulary term: an in-place anchors[] <- assignment recycled the shortened result back to the original length instead of shrinking, duplicating an earlier term in get_centroid() (double-weighting it) and crashing or corrupting get_direction() when the row count changed unevenly
• fixed a typo in find_transformation()'s documentation ("simplying" → "simply"; "et a." → "et al.")
• fixed a flaky parallel-CMDist test that only failed under core-limited check environments (e.g. _R_CHECK_LIMIT_CORES_, as R CMD check sets): the test requested more threads than its reduction logic could ever let survive the final row-count check
• fixed CoCA() silently computing nonsense (NaNs produced) instead of disabling filter_sig when given exactly 2 directions: the guard compared ncol() of the CMD score data frame (which includes a doc_id column) directly against 3, off by one relative to the actual direction count
• fixed CoCA() crashing with an opaque dim(X) must have a positive length error when given exactly 1 direction; it now errors upfront with a clear message, since document correlations are undefined with fewer than 2 directions
• fixed CMDist(cw =, missing = "remove") crashing with an opaque invalid character indexing error when a multi-word cw phrase (e.g. "critical thinking") had only some of its words missing from the embeddings: .check_term_in_embeddings() compared whole phrases against the list of missing individual words, so a partially-missing phrase was never actually dropped from cw despite the removal message saying otherwise; it now drops the whole phrase if any of its words is missing
• fixed CMDist(cv = <0-row matrix>) crashing with an opaque 'names' must be a character vector error; it now errors upfront with a clear message
• fixed weight_ppmi(smooth > 0) triggering a Matrix package deprecation warning (as(<dgeMatrix>, "dgCMatrix") is deprecated); now coerces via "CsparseMatrix", matching the pattern used elsewhere in the package
• fixed CMDist(parallel = TRUE, sens_interval = TRUE) crashing with task 1 failed - "invalid first argument" whenever threads made a worker's chunk exactly 1 document: a missing drop = FALSE collapsed that 1-row chunk to a bare vector before resampling
• fixed get_centroids(groups =) erroring with an opaque missing value where TRUE/FALSE needed whenever groups contained NA; rows with a missing group label are now excluded from every centroid, with a message, matching how empty factor levels are already handled
• fixed find_projection()/find_rejection() silently returning a matrix of NaN for an all-zero vec; both now error with a clear message
• fixed test_anchors(method = "pairdir") crashing with an opaque attempt to set 'rownames' on an object with no dimensions error with exactly 1 anchor pair; it now errors upfront with a clear message, since pairwise cosine similarity is undefined with fewer than 2 pairs
• fixed find_transformation(method = "retrofit") crashing with an opaque inherits(wv, "matrix") ... is not TRUE error when the shared vocabulary between wv and ref was smaller than wv's embedding dimension; it now errors upfront with a clear message, since retrofitting needs at least as many shared terms as dimensions to recover
• fixed get_direction(method = "PCA") silently returning a meaningless unit vector with only 1 anchor pair (a single centered row degenerates in prcomp()); it now errors upfront with a clear message, since PCA needs at least 2 anchor pairs
• fixed get_regions(k_regions > nrow(wv)) crashing with an opaque invalid 'data' error, several steps removed from the real cause (ClusterR::KMeans_arma doesn't raise an R condition on this input — it prints a message and returns a character string in place of a matrix); it now errors upfront with a clear message
• dtm_stopper(stop_termrank =) now warns when the threshold is at or above the DTM's term count, since this silently removed the entire vocabulary with no indication
• dtm_builder() now errors with a clear message when text or doc_id contains NA (previously the NA silently became a real column/row name), and when vocab is empty or contains duplicate terms (previously produced literal duplicate DTM columns, with later duplicates silently all-zero, or a silent 0-column DTM)
• doc_centrality(two_mode = FALSE) now errors with a clear message on a non-square input instead of silently computing meaningless row sums across mismatched columns (only affected method = "degree"; "between"/"eigen"/"span" already failed loudly via their underlying dependency)
