attach_package: Organise temporarily needed packages

In frankRuehle/systemsbio: Streamlined Analysis and Integration of Systems Biology Data

Description

Attach required packages which may be detached after function run.

Usage

attach_package(pkg.cran = NULL, pkg.bioc = NULL, update_bioc_pkgs = F)

detach_package(pkg)

Arguments

pkg.cran	Character vector with names of CRAN packages to attach
pkg.bioc	Character vector with names of Bioconductor packages to attach
update_bioc_pkgs	logical. When FALSE, BiocManager::install() does not attempt to update old packages. When TRUE, update old packages according to ask.
pkg	Character vector with names of packages to be detached

Details

Help functions to organise package loading. Some functions require huge annotation packages which shall not be loaded for the full session. The function attach_package attaches these packages for an individual function run and installes them from CRAN and/or Bioconductor if necessary. detach_package can be used to detach these packages after function run. DLLs of unloaded packages are removed as well.

Value

character vector with package names which have not yet been attached to workspace before call of attach_package. This vector may be used to detach packages not needed any more with detach_package. detach_package invisibly returns the set of identified stray DLLs reported by R.utils::gcDLLs.

Functions

• attach_package: Attach and install packages.

• detach_package: Remove packages not needed anymore
