R help - Jan 2000 - long character data

Hi,
When trying to generate very long strings, my R hangs without any error
message, even if given much memory.

# e.g.
x <- character(10)
for (i in 1:10) x[i] <- paste(1:1000, collapse="abc")
paste(x, collapse="")

# or directly
paste(1:10000, collapse="abc")

Am I violating any max(nchar(character())) or is this a bug?

Regards

[R 0.90.1 on Windows, GUI console I presume.]

The problem is in displaying them on the Rgui console: this will work in
Rterm and other versions of R.

This is already fixed for rw0990.
