Hi, everyone! I am now using for my program, and found it a powerful tool.  I found it easy to connect R using and do plots, but it could'nt catch any errors from R. For instance, when I write a wrong experssion, nothing happened, with no error message. Is there any function could catch error message from right now? Thanks!
