CRAN Matrix Of Available Binary Packages (archivedb.rda)

Description

binarydb_down downloads the matrix of the packages available in binary format available in CRAN (Windows or macOS depending the computer), saves it it in a file named binarydb and finally loads it in .GlobalEnv under the name binarydb. It is a wrapper around the function available.packages(type = "binary").

binarydb_load loads the file filename in .GlobalEnv under the name binarydb.

When loaded in .GlobalEnv, binarydb is recognized by the functions p_vers and p_vers_deps to compare the package version numbers of the installed packages with the most recent versions of the binary and the source versions available in CRAN.

Usage

binarydb_down(dir = ".", repos = getOption("repos")[1])

binarydb_load(filename = "binarydb.rda")

Arguments

dir	character. The directory where "binarydb.rda" is saved Default value "." is the current directory.
repos	character. The address of your local CRAN.
filename	character. The (path to a) file "binarydb.rda" or an equivalent.

Examples

## In real life, to get the latest version, use
## binarydb_down()
## Here, we use a small file
binarydb_load(system.file("data", "zbinarydb.rda", package = "RWsearch"))
class(binarydb)
colnames(binarydb)
dim(binarydb)
head(binarydb)
