[R] inconsistency in tryCatch...

[akshay kulkarni]

Dear Jeff,
               Thanks! I think it is an idiosyncrasy of tryCatch? The other arguments like "error" doesn't need to be assigned to a call right? Just the definition would be sufficient, i think?

Yours sincerely,
AKSHAY M KULKARNI

You defined a function. You did not call the function. tryCatch returned the object you defined. So the interactive console printed the object returned.

Invoking the "function" function does not call the defined function for you. Try:

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