htly trickier with an integer vector:
intvec <- c(4,4,5,6,6,6)
table( intvec )[intvec]
intvec
NA NA NA NA NA NA
as.vector(table( intvec )[as.character(intvec)])
[1] 2 2 1 3 3 3
So I think this will always work for vectors of either type:
as.vector(table( as.character(vec) )[as
ork, but is it OK?:
ave( rep(1, length(charvec)), as.factor(charvec), FUN=sum )
[1] 1 2 3 2 3 3
I suspect that ave() isn't the best choice, but what is the best way to do
this?
Thanks in advance.

The read.table.ffdf function in the ff package can read in delimited files
and store them to disk as individual columns. The ffbase package provides
additional data management and analytic functionality. I have used these
packages on 15 Gb files of 18 million rows and 250 columns.

ersion as expected. That's an
Octave problem, so I'll deal with them on that one. I might not have zlib
compiled in, or maybe they still have a bug in that function.
Thanks!

I don't know why it shows 17 digits and doesn't round to 15, but it is showing
that the numbers are different, for some reason.
Aiding my weakenin
some small amount so that machine precision isn't
constantly causing annoying output?

I thing it is an undesirable feature that write.table() has to try to use
so many digits -- all the way out to eps -- because it causes these kinds
of inconsistencies. Is there no way to get it to put out numbers in the
obviously desirable way without having to write format statements?

I don't think so. I think some of your numbers differ sufficiently from
numbers with only a few digits to the right of the decimal that
write.table needs to write them with increased precision. You didn't
read them like that, didn't you? You did some
