chron and R 2.8

I found the library where all of the older packages are located.

library(chron, lib =
"/Library/Frameworks/R.Framework/Versions/2.7/Resources/library")

Error in dyn.load(file, DLLpath = DLLpath, ...) :
 unable to load shared library
'/Library/Frameworks/R.Framework/Versions/2.7/Resources/library/chron/libs/i386/chron.so':
 dlopen(/Library/Frameworks/R.Framework/Versions/2.7/Resources/library/chron/libs/i386/chron.so,
6): Library not loaded:

 Referenced from:
/Library/Frameworks/R.Framework/Versions/2.7/Resources/library/chron/libs/i386/chron.so
 Reason: image not found
Error: package/namespace load failed for 'chron'

The code above works with zoo
library(zoo, lib =
"/Library/Frameworks/R.Framework/Versions/2.7/Resources/library")

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)

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.

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:

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?

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.

considerable time speed up over both R 2.8 and chron 2.3-24 and

Suppose you find that the library that contains chron in

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

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

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

annoying little problems of being mammals.
