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 - Start
to the first
section of the talk, Prev
to the previous section, Curr
to the
start of the current section, and Next
to the next section.
In addition to the automatic menu items, a user can add buttons to the GUI that accomplish similar purposes.
The use of chunk
in the R code is equivalent to the use of
segment
in the documentation.
