pacs_lifeduration {pacs}

Packages life duration for a specific version

Description

packages life duration for certain versions.

Usage

pacs_lifeduration(
  pacs,
  versions,
  source = c("crandb", "loop_crandb", "loop_cran"),
  lib.loc = .libPaths(),
  repos = biocran_repos()
)

Arguments

pacs

character vector of packages names.

versions

character vector of packages versions.

source

character one of c("crandb", "loop_crandb", "loop_cran"). The "crandb" works if less than getOption("pacs.crandb_limit") (currently 500) packages are looked for. When crandb linked source is used then options(pacs.crandb_ntry = 3) and options(pacs.crandb_nsleep = 0.001) can be used to control the fetch. "pacs.crandb_ntry" can be used to set the maximum number of try outs, by default 3. "pacs.crandb_nsleep" can be used to set the sleep duration between fetch try outs, by default 0.001. Default: "crandb"

lib.loc

character vector of search paths with local packages. Default: .libPaths()

repos

character vector of repositories URLs to use. By default checking CRAN and newest Bioconductor per R version. Default pacs::biocran_repos()

Value

data.frame with two columns package name and life duration.

Note

Results are cached for 30 minutes with memoise package. The crandb R packages database is a part of METACRAN project, source: Csárdi G, Salmon M (2022). pkgsearch: Search and Query CRAN R Packages. ⁠https://github.com/r-hub/pkgsearch⁠, ⁠https://r-hub.github.io/pkgsearch/⁠. For source = "loop_cran"the function will scrap two CRAN URLS. Works only with CRAN packages. Please as a courtesy to the R CRAN, don't overload their servers by constantly using this function.
