Dear list, sometimes my function generates too much data and shows them on screen, i cannot view first several lines until program ends and I have to scroll my mouse up to get them. Is there any re-direction function in R to pipeline outputs to "more" or "less" type functions? Thanks mike [[alternative HTML version deleted]]
maybe ?sink() or ?capture.output() could be useful, in this case.
Best,
Dimitris

Something like
less <- function(a){
fn <-
paste(tempdir(),"\\dataframe.txt",sep='',collapse='')
write.table(a, quote=F, file=fn)
system(paste("less ",fn))
}
could perhaps help you (assuming that you have less on your computer). I agree
that it would be very nice to have a built-in version...

No - not like page().
