With just a few commands in the R console, you can effortlessly initiate the upgrade process, making it ideal for users who prefer a straightforward and user-friendly approach.

Following the installr package, using the Chocolatey package manager also offers a relatively easy way to update R. However, it does come with some drawbacks. Before utilizing Chocolatey, you need to install the package manager itself, which adds an extra step to the process. Additionally, using Chocolatey requires knowledge of running PowerShell commands, which might be unfamiliar to some users. Despite these minor challenges, updating R once Chocolatey is set up becomes a relatively streamlined task.

On the other hand, manually installing a new version of R is the most cumbersome method for upgrading. This process involves downloading the latest R installer, running the installation package, and ensuring that all dependencies are properly managed. It requires more manual intervention and is prone to errors or compatibility issues. Consequently, it is generally considered the least convenient option for users seeking a quick and hassle-free upgrade experience.

Considering the ease of use, the installr package with its updateR() function stands out as the simplest and most user-friendly method for upgrading R. However, depending on individual preferences and technical proficiency, users may opt for the Chocolatey package manager or manual installation when needed.
