[kepler-users] Different behavior of an R script in R terminal and R actor of Kepler

[Christopher Brooks]

Hi Joseph M.,
This could be an internationalization issue with Ptolemy II.

ptolemy/actor/gui/ConfigurationApplication.java contains this code

The way I would approach this is to build Kepler using Eclipse and then 
try setting
a different locale by editing the above code.

I'm sorry Ptolemy II has this restriction, I find it somewhat embarrassing.
