chron and R 2.8

Please provide the input file so its reproducible.
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)
}

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.

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?

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/

The code above works with zoo

To run the old version of chron that you have under 2.7.2
into 2.8.0, on 2.7.2 issue the command (note initial dot):

.libPaths()

Suppose you find that the library that contains chron in
2.7.2 is "/a/b".

Then on 2.8.0 ensure that you don't have chron on the search path

search()

and if you do detach it:

detach("package:chron")
search() # should no longer be there

Then run this where "..." is the library that the old version of chron
is in under 2.7.2.

library(chron, lib = "...")

To run the new version of chron detach the old version and just use:

library(chron)

Yes
chron 2.3-25

Gabor I don't know how to start up another verison of R on the mac.  I
will figure this out, and get back to you (I can then test both of
them side by side).

other fast installation (version numbers from description files in R
2.7.2 directory)
chron 2.3-24
zoo 1.5-4
Mac OS X 10.5.5

thanks

Are you using the same version of chron both times?

has anyone had problems with the upgrade to R 2.8 and chron date
classes.  I have a large zoo object that has a chron index, and it is
taking 5x or so longer to do the same calculation as with 2.7 if it
doesn't fail.  I will provide anything necessary I am not entirely
sure what ya'll would need if anything to try and reproduce the
behavior.  I am using the package StreamMetabolism.
