[R] numbers and decimal points

[janet rosenbaum]

I have a question for our European readers:  how common is it to use
commas as decimal points in spread-sheet and statistics applications?

Is it an inconvenience to require that all data use a period as decimal point?
(i.e., 3.14159 rather than 3,14159).

We're trying to make our program as foolproof as possible, and would
prefer not to give users a chance to have commas as both decimal points
and field delimiters.

Thanks,
