Hi,
Is it possible to comment demo() files? I am trying to write
demos that have comments, R commands, and R output so that new
users will be able to follow along.
I have tried readline(), but that returns the readline("...")
command statement as well as the output from readline, and the
demos are ugly. I have also tried:
options(echo = FALSE)
print("my comments here")
options(echo = TRUE)
[some R commands here]
options(echo = FALSE)
print("more comments")
options(echo = TRUE)
but options() seems to work only at the beginning of the file.
Is there a special command or procedure that I should use?
Thanks,
Olivia Lau
