Package index • pkgmatch

Main functions

pkgmatch_similar_fns(): Identify R functions best matching a given input string

pkgmatch_similar_pkgs(): Find R packages matching an input of either text or another package

BM25 functions

pkgmatch_bm25(): Calculate the "BM25" = "Best Matching 25" ranking function between text input and all R packages within specified corpus.

pkgmatch_bm25_fn_calls(): Calculate a "BM25" index from function-call frequencies between a local R package and all packages in specified corpus.

Embeddings functions

pkgmatch_embeddings_from_pkgs(): Return raw language model ('LM') embeddings from package text and function definitions.

pkgmatch_embeddings_from_text(): Return raw language model ('LM') embeddings from a vector of text strings.

Treesitter functions

pkgmatch_treesitter_fn_tags(): Use "treesitter" to tag all function calls made within local package, and to associate those calls with package namespaces. This is used as input to the pkgmatch_bm25_fn_calls function.

Ollama functions

get_ollama_url(): Get the URL for local ollama API

ollama_check(): Check that ollama is installed with required models, and download if not.

set_ollama_url(): Set the URL for local ollama API

head(<pkgmatch>): Head method for 'pkgmatch' objects

pkgmatch_browse(): Open web pages for pkgmatch results

pkgmatch_load_data(): Load embeddings generated by the pkgmatch_embeddings_from_pkgs function, either for all rOpenSci packages or, if fns = TRUE, all individual functions within those packages.

pkgmatch_update_cache(): Update all locally-cached pkgmatch data to latest versions.

print(<pkgmatch>): Print method for 'pkgmatch' objects

text_is_code(): Estimate whether input text string is code or English prose text.

Data update functions

pkgmatch_update_data(): Update pkgmatch` data for both CRAN and rOpenSci packages on GitHub release
