[R] Comparison of numeric and character vectors

Hi all,
I just discovered that R considers characters to be really big:
> "a" > 999
[1] TRUE
> "a" > 9e307
[1] TRUE
> "a" > 9e308
[1] FALSE
and that some characters are literally infinitely big:
> "Z" >= Inf
[1] TRUE
although not all:
> "a" > Inf
[1] FALSE
This came as a surprise to me (although it is quite possibly a trivial
issue), and I'd appreciate any information about why R considers
character vectors to even be comparable to numeric vectors, and why it
considers characters to have very large values.
Thanks!
Ista
