[R-SIG-Mac] wish: faster resizing of R console window in R.app

[Jochen Laubrock]

Dear Simon et al.,

in longer sessions with real data, the console window often fills up with output. If it is then resized, R becomes unresponsive and the OS X beach ball of death is often seen, with some delay, for an extended period. The following example illustrates this effect (if not, increase the numbers):

omp <- getOption("max.print")
options(max.print=2*1e6)
print(data.frame(matrix(nrow=1e5, ncol=20)))
options(max.print=omp)

This is probably nontrivial, but it would be nice if calculation of the resized window could be faster. Maybe, only refresh the visible portion of the console could be redrawn immediately, and the remainder be recomputed in the background?

Best, Jochen
