It looks to me that it does more or less the same as format().
Maybe I didn't explain myself correctly then. I would like to set the
number of decimal by default, for the whole R session, like I do with
options(digits=6). Except that digits sets up the number of digits
(including what is before the "."). I'm looking for some option that
will let me set the number of digits AFTER the "."
Example: I have 102.33556677 and 2.999555666
If I set the number of decimal to 6, I should get: 102.335567 and 2.999556.
And that for all numbers that will be in/output from R (read.table,
write.table, statistic tests, etc)
Or is it that I didn't understand everything about formatC() and sprintf()?
You didn't:
formatC(x, digits=6, format="f")
[1] "102.335567" "2.999556"
sprintf("%12.6f", x)
[1] " 102.335567" " 2.999556"

Hi everybody,
I'm trying to set the number of decimals (i.e. the number of digits
after the "."). I looked into options but I can only set the total
number of digits, with options(digits=6). But since I have different
variables with different order of magnitude, I would like that
they're all displayed with the same number of decimals.
I searched for it and found the format() function, with nsmall=6, but
it is for a given vector. I would like to set it for the whole
session, as with options.
Can anyone help me?
Thanks in advance
Ivan
