there is no `[<-.IDate` method to ensure the
replacement value is converted to integer. And, in fact, `[<-.Date`
calls as.Date() and data.table::as.Date.IDate() calls as.numeric() on
the IDate object. So the problem exists, and can be fixed, in
data.table.

This could be done by a public third-party repository, independent of
CRAN. However,
your
idea, they will use your new repositories instead of CRAN. There is
no reason to impose this change on all world-wide CRAN users.

Please, please, please read the documentation before sending more
questions to the list. You also have the source code, so you can look
at what "R CMD build" and "R CMD INSTALL" are doing.

How about:
y <- rep(NA,length(x))
y[duplicated(x)] <- match(x[duplicated(x)] ,x)

It seems to be caused by '...' not being passed in as.POSIXlt.factor.
Would it make sense to change the function to pass '...'? I.e. from:
as.POSIXlt.factor <- function(x, ...) as.POSIXlt(as.character(x))
to:
as.POSIXlt.factor <
I believe options(error=recover) will do what you want.

Hi Mark,
The first thing that jumps out to me is that 2.7.1 compiles JRI, while
2.9.1 does not (for some reason, autodetect decides not to compile).

Gostan,
This is not a bug. You're asking for 20 decimal digits of precision,
which is impossible with double-precision floating point arithmetic.
