Hi,

sorry for the last sentence, i was trying to make a generic statement by writing "function"
So the code has to be:

# Save error mesage:

   error1 <- file("error1.txt", open="wt")    sink(error1, type="message")
   experiment <- somefunction(data)

(I mean no matter what function is...)

error1 is not a variable, y can't watch what contains, it is only the definition of a file....

What i wanted was in fact to create a variable with the error message, I can do it of course by reading the file, but my question is about doing it directly.
Thanks
