evaluate
(Package: evaluate) :
Evaluate input and return all details of evaluation.
Compare to eval, evaluate captures all of the information necessary to recreate the output as if you had copied and pasted the code into a R terminal. It captures messages, warnings, errors and output, all correctly interleaved in the order in which they occured. It stores the final result, whether or not it should be visible, and the contents of the current graphics device.
