pacman Package in R

In this article, we will be discussing briefly the pacman package with its working examples in the R programming language.

Pacman Package in R

Tyler Rinker, Dason Kurkiewicz, Keith Hughitt, Albert Wang, Garrick Aden-Buie, and Lukas Burk created the Pacman R package. The package contains tools for easily managing add-on packages in the R programming language. The package relies on Base R functions as a library() and install.packages() and merges them into new, more intuitive, and efficient procedures.

To use the functions provided in the Pacman package, we must first install and load the package to R: After running the aforementioned lines of code, we may use the Pacman package’s functionality.

R

install.packages("pacman")
library("pacman")

Using the load Function to Install and Load Multiple R Packages. Here, we will look at how to use the p load method to load  the  three packages ggplot2, dplyr, and stringr after running the prior code, add on packages in a single line of code below code:

R

# We will install and then load packages
p_load(ggplot2, dplyr, stringr)

Using the pacman package to update Outdated R Packages:

In this example, we will look at how to utilize the Pacman package’s p update function to check for outdated packages and then update them all.

First, let’s see whether of my packages is out of date:

R

p_update(update = FALSE)

Output:

[1] “jakarta”  “honeyloom”      “gfg.table” “othertask”    “ggplot2”    “isoband”   

[7] “anomaliy”   “risic”    “lineworker”  “rookiepool”

Fortunately, the Pacman package provides a simple way for updating all outdated packages with a single line of R code. Before running the following R code, make sure you have some time. This could take some time depending on how many packages you need to update:

R

# Update all the packages
# in the module
gfgUpdate()

p unload Function

The p unload function is another useful feature of the Pacman package. The p unload function can be used from within R to unload one or more loaded packages. Let’s use the p unload command to uninstall the three packages we previously loaded: ggplot2, dplyr, and stringr:

R

# Unload the packages, and then continue
p_unload(ggplot2, dplyr, stringr)
