Create a mini version of CRAN containing only selected packages

## Introduction

At the end of 2014, CRAN consisted of more than 6,000 packages, and by 2017 this number doubled to more than 12,000.  Many organisations need to maintain a private mirror of CRAN, but with only a subset of packages that are relevant to them.

The `miniCRAN` package makes it possible to create an internally consistent repository consisting of selected packages from CRAN-like repositories.  The user specifies a set of desired packages, and `miniCRAN` recursively reads the dependency tree for these packages, then downloads only this subset.  

## Important functions:

Function           | Use it for

--------------     | ------------------------------------------

`pkgDep()`         | Find package dependencies

`makeRepo()`       | Make repository (with or without downloading packages)

`addPackage()`     | Add additional packages (and their dependencies) to existing repository

`updatePackages()` | Update the versions of packages currently in the repository

## Installation:

Get the stable version from CRAN:

```r

install.packages("miniCRAN")

library("miniCRAN")

```

### Development version

Get the latest development version from github:

```r

# Use `devtools` to install directly from github

library(devtools)

install_github("andrie/miniCRAN")

```

## Example:

```r

# 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"))

```
