[R] Outputting variable names and their value bindings

[Jeff Newmiller]

Yes and no. R does not have a "Matlab-output-compatibility" mode, but you can write your script to output anything you want it to using the "cat" function with various functions like "sprintf" and "as.character". You may want to write some functions that format some common objects that you typically output. Then just make sure to use those functions instead of the standard "put an object alone on a line" method of printing.
