[R] reading large numbers

[Sarah Goslee]

I believe you were already answered.

Nothing is happening to your numbers. The default digits
used to *display* your numbers is too small to show all
the decimal places.

There's nothing to worry about; full precision is being used
for all calculations.

But if for some reason you'd like to see them, you can
change the default digits used for printing:

> as.numeric(4398801.3)
[1] 4398801
> as.numeric(439880.3)
[1] 439880.3
>
> options()$digits
[1] 7
>
> options(digits=14)
>
> as.numeric(4398801.3)
[1] 4398801.3
> as.numeric(439880.3)
[1] 439880.3
