The shiny app dependencies

the shiny app dependencies packages are checked recursively. The c("Depends", "Imports", "LinkingTo") DESCRIPTION files fields are checked recursively. The required dependencies have to be installed in the local repository. The default arguments setup is recommended.

app_deps(
  path = ".",
  fields = c("Depends", "Imports", "LinkingTo"),
  lib.loc = .libPaths(),
  local = TRUE,
  base = FALSE,
  description_v = FALSE,
  recursive = TRUE,
  repos = biocran_repos()
)

Arguments

path

character path to the shiny app. Default: "."

fields

character vector listing the types of dependencies, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Character string "all" is shorthand for that vector, character string "most" for the same vector without "Enhances", character string "strong" (default) for the first three elements of that vector. Default: c("Depends", "Imports", "LinkingTo")

lib.loc

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

local

logical if to use local repository (or newest remote packages). Default: TRUE

base

logical if to add base packages too. If TRUE then pacs::pacs_base() are taken into account. Default: FALSE

description_v

logical if the dependencies version should be taken from description files, minimal required. By default installed versions are taken. Default: FALSE

recursive

logical if to assess the dependencies recursively. Default: TRUE

repos

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

Value

character vector with dependency packages or data.frame when checking recursively.

Note

renv package has to be installed.

Examples

if (FALSE) { # \dontrun{
library(renv)
# Please update the path to the custom shiny app
app_path <- system.file("examples/04_mpg", package = "shiny")
pacs::app_deps(app_path)
pacs::app_deps(app_path, recursive = FALSE)
} # }
