R: Installing, Loading, and Detaching Packages

To install a package in R, the function to be used is install.packages. Let say we want to install the ggplot2 package, simply code this with the following:

install.packages("ggplot2")

To install more than one package, utilize the concatenate function, c

install.packages(c("tseries", "forecast"))

Note that in executing the above codes, a dialogue box will pop up asking for the CRAN-Mirror, just choose the one that's in or near your country. Now to load these packages, run

	library(tseries)
	library(forecast)
	#or
	require(tseries)
	require(forecast)

	detach("package:forecast")
