Does the function "c" have a character limit?

For some reason, the R console does not display a ">" symbol,
indicating that it has completed the function, but displays a "+"
symbol instead, which indicates that the function is still waiting
for more input.

If I copy&paste from your message into an R session, it seems to work
for me. I think the reason for that is because what was a single long
line has been wrapped into a lot of shorter lines.

Best regards,
