Re: chron and R 2.8

Two things to try:

- try running both under 2.7.2 instead of trying both under 2.8
- if you know how to build packages from source then try rebuilding the
chron you have under 2.7.2 using 2.98.  You can find it here:
http://cran.r-project.org/src/contrib/Archive/chron/

Re: chron and R 2.8

I have built chron 2.3-24 under 2.8 and it is acting the same as
2.3-24 and as to the previous email the zoo version is the same for
both.  My next test will be to get 2.7.2 up and running again, and see
what the behavior is under this version with the different versions of
chron.  I have not figured out how to install || versions of R in mac
OS X it looks like the packages are maintained but the application is
automatically removed and updated into the current version.  What else
should I try?

Re: chron and R 2.8

The key thing to do is to provide some reproducible code that
someone else can use to verify the problem even if you have
to use it on 2.7.2 with the old chron and 2.8.0 with the new chron.

Re: chron and R 2.8

These are the two functions that I use to read the data in.  I have
reverted back to R 2.7.2, chron 2.3-24, zoo 1.5-4, StreamMetabolism
0.03.  This configuration works just fine- like I expect and with
considerable time speed up over both R 2.8 and chron 2.3-24 and
2.3-25.

fmt.chron <- function (x)
{
    chron(sub(" .*", "", x), gsub(".* (.*)", "\\1:00", x))
}

read.production <- function (data)
{
    read.zoo(data, sep = ",", FUN = fmt.chron, header = TRUE)
}

        DateTime RM215Temp
800  1/9/06 7:46     11.12
801  1/9/06 8:01     11.11
802  1/9/06 8:16     10.98

Please provide the input file so its reproducible.

Re: chron and R 2.8

I've had an offline conversion with Stephen about this and it seems
that in R 2.8.0 order is much slower when applied to chron objects
than previously.

The fix for zoo users is to enter this line (which is already in the development
version of zoo) before using any chron objects from zoo in your session:

ORDER.chron <- ORDER.dates <- ORDER.times <- function(x, ...)
order(as.numeric(x), ...)
