Details

The function presentTalk is a tool that facilitates lectures and workshops in R. The function allows the presenter to show code snippets alongside their execution, making use of R's graphical capabilities. When presentTalk is called, a graphical user interface (GUI) is launched that allows the user to control the flow of the talk (e.g., switching between talks or skipping to various sections of a talk. The automatic control buttons allow the user to move forward or backward in the talk. The GO button moves forward one tag segment, the Back button moves back to the previous tag segment. The blue buttons allow movement among sections -- Prev to the previous section, Restart to the start of the current section, and Next to the next section. Drop down lists are provided for both indicating the current section and slide number and as an additional interface for jumping between different sections or slide numbers. In addition to the automatic menu items, a user can add buttons to the GUI that accomplish similar purposes.
