irequire

Require a Package with User Interaction

Description

Like base require, irequire tries to find and load a package, but in an interactive way, i.e. offering the user to install it if not found.

Usage

irequire(
  package,
  lib = NULL,
  ...,
  load = TRUE,
  msg = NULL,
  quiet = TRUE,
  prependLF = FALSE,
  ptype = c("CRAN-like", "BioC", "BioCsoft", "BioCann"),
  autoinstall = !interactive()
)

Arguments

`package`	name of the package
`lib`	path to the directory (library) where the package is to be looked for and installed if agreed by the user.
`...`	extra arguments passed to `install.packages`.
`load`	a logical that indicates if the package should be loaded, possibly after installation.
`msg`	message to display in case the package is not found when first trying to load/find it. This message is appended to the string `"Package '<packagename>' is required"`.
`quiet`	logical that indicates if loading a package should be done quietly with `require.quiet` or normally with `require`.
`prependLF`	logical that indicates if the message should start at a new line.
`ptype`	type of package: from CRAN-like repositories, Bioconductor, Bioconductor software, Bioconductor annotation. Bioconductor packages are installed using `biocLite` from the BiocInstaller package or fetched on line at http://bioconductor.org/biocLite.R.
`autoinstall`	logical that indicates if missing packages should just be installed without asking with the user, which is the default in non-interactive sessions.

Value

TRUE if the package was successfully loaded/found (installed), FALSE otherwise.
