I apologize for being unclear in my original post. What I am trying to
achieve is to capture the stdin() connection and read in a single
keystroke - including arrow keys and the like - without having to have to
use the return key each time. My goal is to create a small UI for rapidly
looking through the results of a large simulation. As I think about it
more, though, it is probably going to be easier to dump the data into
files and look through it outside of R.
Thanks anyways,
Jon

Is the room still a room when its empty? Does the room,
the thing itself have purpose? Or do we, what's the word... imbue it.

?strsplit
x - ThisIsaString
y- strsplit(x,)
This gives a list, which you can convert to a vector by unlist(y)
Incidentally, you could have found out about strsplit via R's
help.search(character string) (or similar) or even googling R
string function . Please use R's native Help capabilities before
posting to the list.
(I will grant that the unlist() trick may not be that easy to find).
Also, it's often worthwhile searching the Help archives first. Peter
Dalgaard answered this same question here a day or two ago.
Cheers,
Bert

I was wondering if there is a way to get read in a single keystroke at
a
time in R as a string, akin to ncurses-style interfaces. I looked into
readLines, readChar, etc. using stdin, but these all require the use
of an
end of line. Has anyone ever had need to do this or have any ideas on
how
to do this?
Thanks,

PS I apologize if this double-sends, but I am having mail client
