Packages life duration for a specific version — pacs

packages life duration for certain versions.

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. 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.

Examples

if (FALSE) {
pacs::pacs_lifeduration(c("dplyr", "tidyr"), c("1.0.0", "1.2.0"))
pacs::pacs_lifeduration(c("dplyr", "tidyr"), c("1.0.0", "1.2.0"), source = "loop_cran")
# last versions
pacs::pacs_lifeduration(c("dplyr", "tidyr"), sapply(c("dplyr", "tidyr"), pacs::pac_last))
