Convert 4 (Man Page) to RMD

The 4 file extension refers to Unix Section 4 Manual Pages, which document special files and device drivers. These files, such as "mouse.4", describe how devices interact with the Unix operating system and are accessed using the "man" utility. Historically, these manual pages have been a fundamental part of Unix documentation, helping users understand and manage system devices.

The RMD file extension stands for "R Markdown Document". It is primarily used in data analysis and reporting workflows within the R programming environment. RMD files allow users to incorporate executable R code, along with text, into a single document, facilitating the creation of dynamic and reproducible reports. The format was introduced as part of the RStudio IDE to streamline the documentation process and enhance data storytelling capabilities. Over time, it has become integral in fields such as data science and academia due to its versatility and ease of use in generating comprehensive reports and presentations.
