Unfortunately this does not work
Because you did not follow his example.

Friends
I am trying to format a number to a string so 2189.745 goes to
"2,189.35"
and 309283.929 goes to "309,283.93"
I have tried to use formatC(X, big.mark=",",drop0trailing=FALSE,
format="f")
but it does not get the number of decimals correct. Specifying
digits
does
not work as that is significant digits. I could use a switch
statement
switching on the size of the number to be formated to set the digits
parameter but that is complex and leaves me insecure that thre may
be
other
problems I have not uncovered.
Is there a simple way of using library functions to insert
big.marks and
get
the number of trailing digits correct? Perhaps some way of using
sprintf?
Try this inserting a round() step before the final printing:
x = 309283.929
formatC(round(x, 2), big.mark=",",drop0trailing=TRUE, format="f")
[1] "309,283.93"
HTH,
Peter
