On a Mac (and noting the the documentation [somewhere that I cannot find right now] warns us the the collation sequence for characters is OS dependent):
require(R.oo)
charToInt("-")
#[1] 45
charToInt("1")
#[1] 49
On both systems, LC_COLLATE/LC_CTYPE/LANG are set to en_US.UTF-8 In Java,FWIW, I get the Mac answer if I use String.compareTo and the Linux answer if I use Collator.compareTo, but the result is consistent on Mac and Linux. Mick Jordan
