[R] Data.frame issue (pls help)

[Ivan Calandra]

Hi,

I cannot really test since your dataframe is completely distorted, but 
what happens if you try: format(QuoteBID, nsmall=5)?
I think it's just a matter of printing, which uses the number of digits 
from options(digits=).

See: ?options, ?format, etc.

But I'm not an expert and cannot really test for this.
