My guess is that your two machines have different setting for locale.  
What does this produce on each of them:


(Note: It would have been part of the information that you were asked  
to provide per the posting guide.)
For questions about unexpected behavior or a possible bug, you should,  
at a minimum, copy and paste the output from sessionInfo() into your  
message. When mentioning version numbers, always use the full version  
number, e.g., `2.6.1', not just `2.6', and also mention the platform  
(Windows, Linux, MacOS X, with their versions). Other potentially  
relevant details include the locale (type Sys.getlocale() at the R  
prompt), and whether you installed a pre-compiled binary version of R  
or compiled it yourself.
