The shiny app dependencies

Description

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.

Usage

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

## Not run: 
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)

## End(Not run)
