R help - Aug 2004 - how to set the number format to pure numeric?

Hello,

I want to export a numeric matrix in pure numeric format, i.e. I want
0.0001 to appear as "0.0001". But it seems the default setting for
write.table is scientific notation, i.e. it will appear as "1e-04".
how to
set the number format to pure numeric? Thank you very much for your help.

cheers,
lichi shi

It's not the default, BTW.  Try 0.002, say.
See ?options and look at `scipen' to alter the rules.
