In jrminter/lwPackageHelpR: Convenience functions maintaining R packages on a system

knitr::opts_chunk$set(echo = TRUE, warning=FALSE)

Introduction

lwPackageHelpR is a light weight R package install and update manager.

Key Functions

There are two key functions:

1. install_new(pkg, repo = "http://cran.revolutionanalytics.com/", libPath = .libPaths()[1]))

2. install_new_github(pkg, repo, libPath)

Examples

Install a new package

This function checks to see if the package is installed. If not, it will install the package. Use it like this:

if( Sys.info()['sysname'] == "Windows"){

    Sys.setenv(JAVA_HOME="")
    print("unset JAVA_HOME for Windows")
}

library(lwPackageHelperR)
install_new('devtools', .libPaths()[1])

Install a new package from github

Here we install the development version of Yihui Xie's xaringan package from github.

``````r if( Sys.info()['sysname'] == "Windows"){

Sys.setenv(JAVA_HOME="")
print("unset JAVA_HOME for Windows")

}

install_new_github('xaringan','yihui',.libPaths()[1])

```
