There's a coercion to character implicit (i.e., the number 999 gets
converted to the string "999") and then comparison is done in lexical
(dictionary) order in which digits are lower than characters.
You'll also note you get apparently strange behavior like "34" < "9"
if you don't think about thin
Dear Ista,
This is a consequence of coercion of the numbers to character:
> c("Z", "a", 999, Inf)
[1] "Z" "a" "999" "Inf"
> sort(c("Z", "a", 999, Inf))
[1] "999" "a" "Inf" "Z"
I hope this helps,
John

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
