Convert PDB PLUCKER to RMD

The PDB (Palm Database) file extension, used with Plucker eBooks, is designed for storing eBooks on Palm OS devices. Plucker, an open-source eBook reader, converts various document formats, including text, PDF, and HTML, into PDB files for offline reading. Introduced in the early 2000s, Plucker facilitated mobile access to digital content before the widespread adoption of modern eBook formats. Its simplicity and open-source nature made it popular among early mobile users and developers.

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.
