After using pipe() to view output in less, the pipe becomes invalid:
$ p <- pipe("less")
$ capture.output(1:100, file=p)
$ p
Error in summary.connection(x) : invalid connection
$ close(p)
Error in close.connection(p) : invalid connection
Is this a bug? Other uses of pipe works differently:
$ p <- pipe("echo 4711")
$ x <- scan(p)
Read 1 item
$ x
[1] 4711
$ p
description class mode text opened can read
"echo 4711" "pipe" "r" "text" "closed" "yes"
can write
"no"
$ close(p)
$ p
Error in summary.connection(x) : invalid connection
Cheers
