Load Multiple Packages at Once in R (Example)


In this tutorial, I’ll illustrate how to load several add-on packages with one line of code in the R programming language.

The article consists of these content blocks:

Let’s dive right in.


Creation of Example Data

As a first step, we need to specify a vector of package names:

my_packages <- c("dplyr", "mice", "stringr")           # Create vector of packages

We have stored the names of three packages in the character vector my_packages. In the next step, I’ll show how to load all of these packages at once…


Example: Load Multiple Packages at Once in R

If we want to load multiple packages at once to R, we can use a combination of the lapply() and require() functions:

lapply(my_packages, require, character.only = TRUE)    # Load multiple packages

After running the previous R code, all packages in the vector my_packages are loaded to R.
