Hello list.
I'm using R from the gnome-terminal in Fedora. My preference is to write
programs in VIM, and then source the file from R, or copy and paste the
lines into the console. I'm wondering if there is a way to increase the
"paste buffer" as an alternative to "sourcing" large analyses. As was
mentioned in a recent thread on Linux GUI's, I find that if I paste in a
large amount of text, the lines end up getting cut off at some point. I
wonder if this is an R restriction, because it seems like I am able to
paste substantially more text in other console-based programs. Is there
any way to increase the amount of text that I can paste into an R
session?
Thanks!
Manuel
Manuel,
Maybe I misunderstand what you mean by "lines end up getting cut off at
some point" so correct me if I got it wrong, but I assume you mean that
after a certain number of lines entered you can no longer scroll back up
and view the earlier lines?
I think that this is not an issue of the scroll buffer, but of buffers
internal to the terminal program or the shell, which are designed to hold
keyboard input and which can be overwhelmed by the rate of input when
large text selections are pasted in, as this appears as though thousands
of keys had been typed almost instantaneously from their view, so to speak.
I did say I was guessing :-)
For these reasons, I generally strongly recommend against pasting into
terminals.
Thanks for this Jan. I haven't noticed this myself but then again I hate
copy/paste and rarely use R outside emacs/ess these days.
In R, use the source() instead... ;-)
Agreed. source("filename", echo = TRUE) will sort of replicate the
behaviour the original poster would get if they like to see the commands
printed among the results. But if he is pasting in that much data,
Manuel will still have to increase the buffer on the terminal,
especially if he is using one of the defaults in FC3 as the output will
quickly get lost.
Best regards, Jan
All the best,
Gav
