[R] How do I format something as "0.000"?

[Christian Hennig]

Hi,

I would like to use the format function to get numbers all with three 
digits to the right of the decimal point, even in cases where there is no
significant digit left. For example, I would like to get
c(0.3456789,0.0000053) as "0.346" "0.000".
It seems that it is not possible to force format to print a "0.000", i.e.
without any significant decimal places.
Is it possible to do this somehow in R?

Thanks,
Christian
