Hi all,
I am trying to do something simple, but which is deviling me. I want to add an
up-arrow to the x-axis, pointing to a specific location on the axis. I want the
arrow to be as large as possible.
Here is where I'm at with my code:

Hi Josh,
Try this...
mtext(expression(symbol(\255)), side=1, line=0, at=7)

Hi Michael,
I'm just curious if you know about a list somewhere where I can find the
number of a specific symbol. What I mean, with your example, is how to
find that an arrow corresponds to \255.
Moreover, Josh wanted the arrow to be really big. Is it possible to make
it bigger? I would be
Hi Ivan,
The help page for plotmath has a list of symbol names such as the one
Barry suggested, and in the References section there is a URL (the
auckland.ac.nz one) for a table of symbols and their numeric codes.

For both Rowlingsons's and Bedward's solutions the request for as
large as possible can be addressed with cex = 5 or some more suitable
value.

Sorry - missed that bit. You can use the cex argument of the mtext
function to make the symbol bigger.

Hi again,
Just one little question. I don't understand what clipping is.
Probably a problem with English...
Therefore the par(xpd=NA) is not really clear for me; nor is the clip()
function. And I don't see any difference between par(xpd=NA) and nothing.
It's not really related to this post,

Dear Michael,
Thanks very much. I have a follow-up question: how did you know that symbol 255
is the up-arrow?

Not sure which ones work in R, but I recently needed injection, surjection,and
bijection arrows,
and found them here : http://unicode.org/charts/#symbols
