R help - Jan 2005 - Naming Convention

I was wondering whether there exists a naming convention for row and column
names in R data frames and matrices.
E.g: PriceSwap or PRICESWAP or PRICE.SWAP

Many thanks.

Dear Reinhold,

All entries are allowed except "price swap" or "price_swap"

Of course it?s most convenient to use short names and small letters for quicker
typing.

Regards
Christoph

Also, while any character string is allowed, the use of strings 
that are not legal names limits their utility, especially for the 
columns of a data.frame, which could normally be used in a formula for 
something like "lm" or even more general using "with" or
"attach".

      hope this helps.  spencer graves
