5. library(tcltk); options(pager=tkpager)
6. options(pager="./mypager") with mypager
cat > /tmp/foo
xterm -e less /tmp/foo &
(getting a unique tempfile name and removing it when you're through
reading is - um - an exercise for the reader)
7. options(pager=function(file, header, title, delete.file)
system(paste("xterm", "-e less", file, "&")))
(getting the title right is going to be tricky: it is generally
something like "R Help on `ls'" and the quotes will confuse the shell)
The latter two obviously only work when less is installed...
