Display a prompt and collect the user's response
ask(msg = "Press <RETURN> to continue: ", con=stdin())
msg |
Character vector providing the message to be displayed |
con |
Character connection to query, defaults to |
The prompt message will be displayed, and then readLines is
used to collect a single input value (possibly empty), which is then
returned.
In most situations using the default con=stdin() should work
properly. Under RStudio, it is necessary to specify
con=file("stdin") for proper operation.
A character scalar containing the input provided by the user.
