I think the problem is that you named your new arrowhead " >"
(meaning the name contains a space). Changing that to something
else seems to fix the problem. Based on an example in the LyX
xy-pic help file, I used a vertical bar (so the first argument to
\newdir is "|>"). I've attached a working (for me at least) LyX file.

Hi
Thanks for that. I had taken the code directly from the XY-pic
User’s Guide. Now, having played with it ANY allowable LYX character
seems to work e.g. x.
There have been other instances where LYX will not allow input of
characters, for instance the tilde ~. I needed this in \ar@{~>}[r]
in xy-pic to produce a squiggly arrow. I eventually forced it in by
pasting into the maths environment. The screen shows LYX thinks
there is a space, the code view shows a tilde, but when trying to
input tilde from the keyboard LYX converts it to \sim which then
throws a compile error.
Cheers
What happens if you escape the tilde (with a backslash)?
I get this
"Xy-pic error: illegal : macro:->\T1-cmd \~\T1\~ not valid."
Yeah, that one's definitely weird. I had to reverse engineer the wiggly
arrow in the LyX xy-pic manual. It turns out that you need to use Insert

inset, you'll see the marker for a space, but if you look at the LyX
code in the Code Preview pane, it will be a tilde ... plus, when you
compile you'll see that it worked.

Yes its annoying. I achieved the right code by cutting ~> from normal
text and pasting it into the maths environment. This seems to stop the
shortcut mechanism changing the tilde to \sim.
