How to Download R for Mac OS X




To download R for Mac OS X, you need to go to the , which is the official repository of R packages and binaries. CRAN stands for Comprehensive R Archive Network, and it hosts thousands of packages and extensions that enhance R's functionality.


On the CRAN website, click on the "Download R for (Mac) OS X" link. This will take you to a page where you can choose a mirror site that is closest to your location. A mirror site is a server that hosts a copy of the CRAN files, so choosing a nearby one will speed up your download.

How to Verify the Installation and Run R




To verify that R has been installed correctly on your Mac, you can open the Terminal application and type R. This will start an interactive session of R in your terminal window. You should see something like this:



R version 4.3.0 (2023-04-21) -- "Already Tomorrow" Platform: x86_64-apple-darwin17.0 (64-bit) ... Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R. >


This shows you the version of R that you have installed, as well as some information about your platform and some tips on how to use R. You can type commands at the > prompt and press Enter to execute them. For example, you can type 2 + 2 and press Enter to see the result:



> 2 + 2 [1] 4


To exit R, type q()y to save it, n to discard it, or c to cancel the exit. If you save it, R will create a file called .RData in your current working directory, which you can load in your next session by typing load(".RData").


How to Install Additional Packages and Update R




One of the great advantages of R is that it has a large and active community of developers and users who create and share packages that extend R's functionality. A package is a collection of functions, data, and documentation that can be installed and loaded in R. There are thousands of packages available on CRAN and other sources, covering various topics and domains.


To install a package from CRAN, you can use the install.packages() function in R. For example, to install the package, which is a popular package for creating beautiful and complex graphics, you can type:



> install.packages("ggplot2")


This will download and install the package and its dependencies from CRAN. You can also specify a vector of package names to install multiple packages at once. For example, to install the package, which is a collection of packages for data manipulation and analysis, you can type:



> install.packages("tidyverse")


To load a package that you have installed, you can use the library() function in R. For example, to load the ggplot2 package, you can type:



> library(ggplot2)


This will make the functions and data from the package available in your session. You can also use the :: operator to access a specific function from a package without loading it. For example, to use the qplot() function from ggplot2, you can type:



> ggplot2::qplot(x = mpg, y = wt, data = mtcars)


This will create a scatter plot of miles per gallon versus weight for the mtcars dataset.


To update the packages that you have installed, you can use the update.packages() function in R. This will check if there are newer versions of your packages on CRAN and install them if there are. You can also specify a vector of package names to update only certain packages.


To update R itself, you can use the package, which is a package that allows you to update R from within R. To use this package, you need to install it first by typing:



> install.packages("installr")


Then, you can load it and run the updateR() function:



> library(installr) > updateR()


This will check if there is a newer version of R available and guide you through the update process.
