miniCRAN (version 0.2.4)

makeRepo: Downloads packages from CRAN to specified path and creates a local repository.

Description

Given a list of packages, downloads these packages to a specified destination folder using the required CRAN folder structure, and finally creates the PACKAGES index file. Since the folder structure mimics the required structure and files of a CRAN repository, it supports functions like install.packages().

Usage

makeRepo(pkgs, path, repos = getOption("repos"), type = "source",
  Rversion = R.version, download = TRUE, writePACKAGES = TRUE,
  quiet = FALSE)

updateRepoIndex(path, type = "source", Rversion = R.version)

Arguments

pkgs

Character vector of packages to download

path

Destination download path. This path is the root folder of your new repository.

repos

URL(s) of the 'contrib' sections of the repositories, e.g. "http://cran.us.r-project.org". Passed to available.packages

type

Possible values are (currently) "source", "mac.binary" and "win.binary": the binary types can be listed and downloaded but not installed on other platforms. Passed to download.packages.

Rversion

List with two named elements: `major` and `minor`. If not supplied, defaults to system version of R, using R.version. Only used if type is not "source"

download

If TRUE downloads packages.

writePACKAGES

If TRUE, calls write_PACKAGES to update the repository PACKAGES file.

quiet

If TRUE, suppress status messages (if any), and the progress bar during download.

# Specify list of packages to download
revolution <- c(CRAN="http://cran.revolutionanalytics.com")
pkgs <- c("foreach")

pdb <- cranJuly2014

pdb <- pkgAvail(
    repos = c(CRAN="http://cran.revolutionanalytics.com"),
    type="source"
  )

pkgList <- pkgDep(pkgs, availPkgs = pdb, repos=revolution, type="source", suggests=FALSE)
pkgList


# Create temporary folder for miniCRAN
dir.create(pth <- file.path(tempdir(), "miniCRAN"))

# Make repo for source and win.binary
makeRepo(pkgList, path=pth, repos=revolution, type="source")

# List all files in miniCRAN
list.files(pth, recursive = TRUE)

# Check for available packages
pkgAvail(repos=pth, type="source")

# Repeat process for windows binaries
makeRepo(pkgList, path=pth, repos=revolution, type="win.binary")
pkgAvail(repos=pth, type="win.binary")

# Delete temporary folder
unlink(pth, recursive = TRUE)
