R is a programming language that is often utilized by statisticians because of its capabilities in statistical computing. This guide describes how to install R on Debian 10.
1. Prepare the Server
- Create a non-root sudo user according to Rcs's best practices guide.
- Follow Rcs's best practices to update the system before installing R.
2. Install R
Install R from the standard repository.
$ sudo apt install r-base -y
3. Test the Installation
Launch R.
$ R
You should see output similar to:
R version 3.5.2 (2018-12-20) -- "Eggshell Igloo"
Copyright (C) 2018 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)
To exit R, type:
q()
Then press Enter. When prompted to save the workspace image, answer Y to save the workspace, N to exit without saving, or C to cancel and return to R.
4. Install Packages
R packages extend the capabilities of R. Packages are only available to the user who installed them unless they are installed by the root user.
Start R.
$ R
Install the package. Replace example with the desired package.
> install.packages("example")
Here is a list of useful R packages.
5. A Demo with txtplot
The txtplot library can output many different kinds of charts in ASCII.
Start R.
$ R
Install the txtplot package.
> install.packages('txtplot')
Load the txtplot package.
> library('txtplot')
Plot the speed and distance required for a car to stop, using R's default datasets package.
> txtplot(cars[,1], cars[,2], xlab = 'speed', ylab = 'distance')
The output looks like this:
+----+-----------+------------+-----------+-----------+--+
120 + * +
