I see no condition object in your example.
This will not be the case when running codes from Winedit or TINN?
Please give us some evidence. If you run interactively a single statement
comtaining stop(), it stops execution of just that statement.
When I do something like:
if(length(content[content%in%folders])!=4) stop("Execution will be
interrupted")
from TINN while executing an entire code R will continue reading the code
anyway.
Just as will pasting multiple lines into an interactive R session -- that
is intentional.
I don't know what you mean by 'TINN' and 'Winedit' (what exact program,
how are you using them?) but suspect that they are working just like
pasting lines into the R session, or R-for-Windows' own pager and script
editor.
Is there a way to interrupt the code of being read from a text interface?
stop() breaks execution of a block of code that source()d -- maybe that is
what you are looking for?
