For instance allow something like: devtools::install_github(repo = "garthtarr/pairsD3")

Also, summarized (and edited) from [https://coderwall.com/p/vuguzq/installing-r-packages-from-cran-bioconductor-omegahat-github]

• [ ] Offline (already downloaded package) Could be usefull e.g. for users with no or slow internet connection, or unpublished packages

install.packages("/home/trendwise/Downloads/R packages/RSPython_0.7-1.tar.gz",repos=NULL,lib=.libPaths()[1])

• [ ] Online R script (which in coderwall.com example allows to install other packages)

# installing biocLite
# required for downloading & installing Bioconductor packages
source("http://bioconductor.org/biocLite.R")
biocLite() # installs automatically 'Biobase' 'IRanges' 'AnnotationDbi' ‘BiocGenerics’ ‘RSQLite’
biocLite(c("GenomicFeatures", "AnnotationDbi"))

Note: does it make sense to allow to execute some code in the DesktopDeployR if some conditions is met, for eg installing something?

• [ ] Omegahat

  install.packages("RCurl", repos = "http://www.omegahat.org/R")
  #  For some packages, there are binaries for Windows.
  # For most others, you will need to specify to download the source package
  install.packages(packageName, repos = "http://www.omegahat.org/R", type = "source")

• [ ] Github

install.packages("devtools")
library(devtools)  # see [https://stackoverflow.com/questions/5595512/what-is-the-difference-between-require-and-library]
 install_github("rplos", "rOpenSci")

• [ ] RForge

  install.packages("audio",repos="http://rforge.net")
  install.packages('knitr', repos = c('http://rforge.net', 'http://cran.rstudio.org'),type = 'source')

These are great ideas. Package "ensure"-ing could potentially incorporate all of these options and handled by a small DSL in the packages.txt file.
