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.
