R and RStudio

Make sure that you have installed the latest versions of R and RStudio.

R packages

R packages are units of shareable code, containing functions that facilitate and enhance analyses. In simpler terms, think of R packages as iPhone Applications. Each App has specific capabilities that can be accessed when we install and then open the application. The same holds true for R packages. To use the functions contained in a specific R package, we first need to install the package, then each time we want to use the package we need to โ€œopenโ€ the package by loading it.

While installing packages you might be prompted:

  There is a binary version available but the source version is later:

<table of package names>

Do you want to install from sources the package which needs compilation? (Yes/no/cancel)

Always enter no followed by enter.

Install the following packages by copying the code below into the Console (usually the left or bottom-left pane in RStudio) after the prompt >.

if (!require(tidyverse)) install.packages("tidyverse")
