savepkglist: Load or save the list of attached packages

In basille/basr: Basic, but hopefully useful, functions

Description

Display, save or load the list of attached packages.

Usage

savepkglist(file = ".Rpackages")

attpkglist()

loadpkglist(file = ".Rpackages")

.loadpkglist()

Arguments

file	The name of the file in which to save the list of attached packages, or from which to load it. The path is relative to the current working directory.

Details

attpkglist simply lists all attached packages (i.e. not base packages).

savepkglist saves the list of all attached packages in a file, with one package per line.

loadpkglist loads a list of packages from a file. The file should contain one package name per line, without quotes, and no empty line. If the packages are not installed, the function sends a warning.

.loadpkglist automatically loads the .Rpackages file at startup (see the Note below).

Note

To automatically load a .Rpackages list at startup, add this in your .Rprofile:

### Load packages at the start of R if the package list exists

basr:::.loadpkglist()

Essentially, the function appends the list of packages at the end of the defaultPackages option (see options for this option; see also Startup for more details about the initialization at start of an R session).
