Description Usage Arguments Examples

View source: R/packages.r

Loads packages. If not available, then an install attempt will be carried out.

1	load.packages(mode=STRING, package=STRING/s, url=STRING/s, mirror=INT, force=BOOL, dependencies=BOOL/STRINGS, quietly=BOOL, stop.on.error=BOOL, lib=STRING, file.type=STRING, version=STRING)

`mode`	one of `'cran'` (Default), `'url'`, `'github'` or `'biocmanager'`. Determines how the package will be loaded. If `mode='url'` is set, then there setting the `package` vector is optional.
`package`	a vector of strings.
`url`	a vector of strings. Either `package` or `url` should be non-empty.
`mirror`	an integer between 0 and (currently) 94. If not set, will ask for user input, upon the first time that CRAN-sources are loaded.
`file.type`	an optional string, e.g. `'zip'` or `'gz'`, to be use under `mode='url'`, if the downloaded file is to be first unzipped.
`lib`	an optional string, the Git-repository name.
`dependencies`	either `TRUE`, `FALSE` or a string-vector. A string-vector is only useful in the case of installing under `mode='url'`, and in this one may use either boolean values or a subset of `c('Depends', 'Imports', 'LinkingTo', 'Suggests', 'Enhances')`.
`force`	if set `TRUE`, will force an installation. If `FALSE` (Default), will first attempt to load the package and then install.
`quietly`	boolean value to control the verbosity of installers.
`stop.on.error`	a boolean value (default `FALSE`). If set as `TRUE`, will stop, if loading any package (after attempting to install it) fails.
`version`	a string for package versioning. Useful only under `mode='biocmanager'`.

## Not run: 
load.packages(mirror=53, package='tidyverse', force=TRUE);
load.packages(mirror=53, package=c('tidyverse', 'Matrix'), stop.on.error=TRUE, force=TRUE);
load.packages(mirror=53, package=c('tidyverse', 'Motrix', 'cowplot'), stop.on.error=TRUE, force=TRUE); # this will stop!
load.packages(mode='github', package=c('RLogik/clusterby', 'RLogik/rbettersyntax'), dependencies=TRUE);
load.packages(mode='github', url='https://github.com/RLogik/clusterby/archive/master.zip', file.type='zip', force=TRUE, dependencies=FALSE);

## require('clusterby') will be tried first, then potentially an install, then a require.
load.packages(mode='github', package='clusterby', url='https://github.com/RLogik/clusterby/archive/master.zip', file.type='zip', dependencies=TRUE);

## End(Not run);
