oops, I forgot to attach the example txt file with the syntax error, so I will
do it here, can anyone see what the error is with bryansAtLineLevel?

Well...

You just can't end vector declaration with a comma...

Error: syntax error

( R 2.0.1 and R 1.8.1 )

  I suspect the error is more to do with the length of the line 
overflowing a buffer, so that R doesn't see the closing parenthesis, and 
then the next line starts with 'x=' (or whatever variable name) so the 
parser sees:

  a = c(1,1,1,
  b = c(1,0,1,1,1,1)

and hence syntax error.

I pasted the long line in interactive mode, and R prompted me for a 
continuation with a '+' prompt, even though there was a closing 
parenthesis on the long line. That made me think it had truncated the 
input.

Further tests reveals the input line is chopped at roughly 1022 
characters, which makes me think theres a buffer[1024] somewhere. Its 
probably documented as well.

You can in R-2.1.0 Patched:

It might be worth pointing out that R is supposed to have a 1024 byte (not 
character) input buffer, and I did fix a few things related to that when 
internationalizing the parser (and also some about multi-byte pushbacks 
which I suspect is the issue here).

It is still good practice to keep input lines well below that buffer size.
