It is a bad idea to do that in any case.
If you have such huge data or code, save the data / code to a file and 
read that one. If it is R code, use source() to do so.

There are buffer sizes and you probably hit one of them. So no need to 
try. You cannot expect Copy & Paste to work for an arbitrarily sized string.
