Create a mini version of CRAN containing only selected packages

At the end of 2014, CRAN consisted of more than 6,000 packages, and by2017 this number doubled to more than 12,000. Many organisations need tomaintain a private mirror of CRAN, but with only a subset of packagesthat are relevant to them.

TheminiCRAN package makes it possible to create an internallyconsistent repository consisting of selected packages from CRAN-likerepositories. The user specifies a set of desired packages, andminiCRAN recursively reads the dependency tree for these packages,then downloads only this subset.

Get the stable version from CRAN:

install.packages("miniCRAN")library("miniCRAN")

Get the latest development version from github:

# Use `devtools` to install directly from githublibrary(devtools)install_github("andrie/miniCRAN")

# Determine and download the packages `ggplot2`, `plyr` and `reshape2`,# including their dependencies:library("miniCRAN")pkgs<- c("ggplot2","plyr","reshape2")makeRepo(pkgDep(pkgs),path= file.path(tempdir(),"miniCRAN"))
