The document provides instructions for installing the reshape2 package in R on different operating systems. The preferred method is to install directly from R or RStudio using install.packages("reshape2") and library("reshape2"). For Linux (Ubuntu), commands are given to install via apt-get. For Mac, specific commands using install.binaries are provided. For Windows, multiple commands using install.binaries from different CRAN links are listed as alternatives.

1. Reshape2 Installation Instructions for R
This method usually works best.
Via RStudio (Regardless or Operating System):
• install.packages(“reshape2”)
• library(“reshape2”)
If the above method has not worked try installing from GitHub as an alternative. Type the command below
directly in RStudio.
Via Github:
devtools::install_github(“hadley/reshape”)
If the methods above did not work you can install via CRAN. When it comes to CRAN there are
different instructions based on the operating system that you use.
Via CRAN:
Ubuntu:
Type the following commands in the terminal:
sudo apt-get update -y
sudo apt-get install -y r-cran-reshape2
Mac:
Type the following command in the terminal:
1) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/macosx/el-
capitan/contrib/3.6/reshape2_1.4.3.tgz"), contriburl = contrib.url(CRAN, type = "mac.binary"),
method, available = NULL, destdir = NULL, installWithVers = FALSE)
2) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/macosx/el-
capitan/contrib/3.5/reshape2_1.4.3.tgz"), contriburl = contrib.url(CRAN, type = "mac.binary"),
method, available = NULL, destdir = NULL, installWithVers = FALSE)
Windows:
Type the following command in the terminal:
1) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/windows/contrib/
4.0/reshape2_1.4.3.zip"), contriburl = contrib.url(CRAN, type = "windows.binary"), method,
available = NULL, destdir = NULL, installWithVers = FALSE)

2. 2) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/windows/contrib/
r-devel-gcc8/reshape2_1.4.3.zip"), contriburl = contrib.url(CRAN, type = "windows.binary"),
method, available = NULL, destdir = NULL, installWithVers = FALSE)
3) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/windows/contrib/
3.6/reshape2_1.4.3.zip"), contriburl = contrib.url(CRAN, type = "windows.binary"), method,
available = NULL, destdir = NULL, installWithVers = FALSE)
4) install.binaries(reshape2, lib, CRAN = getOption("https://cran.r-project.org/bin/windows/contrib/
3.5/reshape2_1.4.3.zip"), contriburl = contrib.url(CRAN, type = "windows.binary"), method,
available = NULL, destdir = NULL, installWithVers = FALSE)
