Indeed. We have no font for them. I use this in my preamble:
\newcommand{\R}{\mathbb{R}}
Then type \R when I want it. This comes out as a red R, which is close
enough for me :-)
IMO, the long-term direction for LyX needs to be to use some more capable
fonts than the X ones it currently uses. Possibly this means building
one of the truetype font libraries into LyX (this would make the on-screen
display significantly more pleasing to the eye, and would allow
anti-aliasing as an option), and using a good unicode font (if such even
exists?).

Hmm. That's not in the standard blackboard font. You'd need to try a
general latex forum for that, I'm afraid. Personally, I find a standard
'1' serves well for the identity in many contexts. Occasionally, I use a
topless iota. Failing that, I use a bold 1. (Note that the doubled line
is in fact a chalk-notation for bold, and should never have made it into
print ;-)

Hmm. The symbosl should be \because and \since. I can't get them to
work, although I have AMS math enabled. Odd.

You can always use the underlying LaTeX notation.
See my other mail about display fonts... (about to be written)
