Ubuntu R users:
The process of sending the newest builds of R 2.14.0 to the CRAN servers
has begun. I would expect to see updates coming to your machines over
the next 24 hours. A couple of items to be aware of/watch out for.
From the latest "R News:
All packages must have a namespace, and one is created on
installation if not supplied in the sources. This means that any
package without a namespace must be re-installed under this
version of R (but data-only packages without R code can still be
used).
This means that some of the packages that you have installed may fail to
load. 'library(foo)' may result in this error:
Error in library(foo) :
package 'foo' does not have a NAMESPACE and should be re-installed
If you installed the package using R (R CMD INSTALL or
install.packages()), you will need to re-install the package. If the
package authors have update their packages, an update will work, but a
re-install will fix ones that have not been updated. If you installed a
package via apt or synaptic (r-cran-foo), please let me know so I can
update the build. I have been trying to fix all of them, but it has
been difficult to find them all.
I have enabled the use of OpenMP. This has been known to break the
revolution-mkl package. If this effects you, one solution is to not
upgrade to 2.14 (or roll back by pinning the old version. Search for
'pinning apt' or 'pinning synaptic' for more information). Another
solution would be to use another package such as OpenBLAS
(http://xianyi.github.com/OpenBLAS/).
Due to other changes 'under the hood', some packages just break. For
example, the package 'sp' would not load until the maintainers updated
the code. If a package fails to load for reasons other than a NAMESPACE
error, check CRAN for updates.
If you have questions or issues, please let me know.
Michael
