[R] inconsistency in tryCatch...

[akshay kulkarni]

Dear Bert,
                 THanks a lot! I don't know how I escaped such a simple reasoning...

Your sincerely,
AKSHAY M KULKARNI

Dear members,
                          I have the following code:

        > tryCatch(function() print("fred"),  error = function(e) sum(1:3), finally = sum(1:3))
         function() print("fred")

The expected output from the tryCatch call should be to print "fred" to the console,
NO! You have simple defined the function -- you have not called/executed it. This defines and calls it:

> tryCatch({function() print("fred")}(),  error = function(e) sum(1:3), finally = sum(1:3))
[1] "fred"

Cheers,
Bert




and exit, but as seen above, it is outputting
          function() print("fred")

Can you people please shed some light on what is happening?

thanking you,
Yours sincerely,
AKSHAY M KULKARNI
