[R] Numbers with correct significant digits

[RMan54]

I think that I answered my own question.

Since formatC is an implementation of the C-style formatting, I thought that
a "#" as flag could work (for g and G conversions, trailing zeros are not
removed  from  the  result  as they would otherwise be). Although not in the
online help, this worked in R as follows:

v  <- c(9.6996, 99.99)
formatC(v, digits=3, format="g", flag="#")

result:

"9.70" "100."

The only small annoyance is that the decimal point is always shown.
