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.
See the PBSmodelling User's Guide for more information.
