There is a page() command in R -- see '?page'. From your query I take it you are in fact using either Linux or Unix (or possible a Mac BSD type OS). Have a look at options("pager") to see what is currently uses. I have modified my R setup so that it uses 'less' (on Linux) as the pager program. I did this in my .Rprofile (in home directory) by putting in the lines: .xthelp <- function() { tdir <- tempdir() pgr <- paste(tdir, "/pgr", sep="") con <- file(pgr, "w") cat("#! /bin/bash\n", file=con) cat("export HLPFIL=`mktemp ", tdir, "/R_hlp.XXXXXX`\n", sep="", file=con) cat("cat > $HLPFIL\nxterm -e less $HLPFIL &\n", file=con) close(con) system(paste("chmod 755 ", pgr, sep="")) options(pager=pgr) } .xthelp() rm(.xthelp) This opens anything which might be paged in a separate xterm, so thatfor instance, all responses to "?....." come up in a new xterm being paged by 'less'. Likewise, if you page a large object (such as a matrix M with 500 rows), using 'page(M), you will again see the result paged in 'less' in a separate window. This code was suggested by Roger Bivand in response to a query of mine back in 2003.
