[R] maximum amount of lines of code to be copy pasted to R console

[Jannis]

Dear list members,


is there any maximum amount of lines of code that can be copy pasted 
into the R console? Or some maximum amount of levels of nested 
parantheses? Whenever I copy paste some big chunk of code into the R 
console I get errors of missing parantheses etc. even though the 
parantheses are balanced (i.e. the code runs when run via source or 
inside some function).



Cheers
Jannis
