Convert RMD to 9 (Man Page)

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.

The 9 file extension refers to Section 9 of the Unix manual pages, specifically covering Kernel Routines. These manual pages provide detailed information on kernel APIs, internal structures, and other essential aspects of kernel development. Developed by Dennis Ritchie and Ken Thompson at AT&T Bell Laboratories in 1971, Section 9 is crucial for kernel developers but is not universally available due to its specialized nature.
