The warning is produced by the getPackageName() function. e.g. getPackageName(parent.env(getNamespace('data.table'))) I was wondering what could be done to get rid of these warnings, which I believe in the case "unloadNamespace" case are irrelevant. The stack of calls is: # where 3: sapply(where, getPackageName) # where 4:...

The function getAllMethods in the methods package uses the non-existent function packageName where I believe the function getPackageName was intended. For example: > getAllMethods("formula") Error in sprintf(gettext(fmt, domain = domain), ...) : could not find function "packageName" The patch to RMethodUtils.R is here: 238c238 < warning(gettextf("'%s' from '%s' is a n...

Hi Kumar, There is an error on your configuration line, you should provide the path to llvm-config binary instead of configure file. Assuming that you compiled llvm in release mode, the llvm-config binary is located in : YOUR_PATH_TO_LLVM/Release+Asserts/bin/llvm-config Try to change the -with-llvm-config-path option and it will compile.

How do you debug methods of a reference class? I've been using mtrace, which is excellent, but i cannot figure out how to mtrace a reference class method. Maybe there is some other way to debug these, for example with ordinary trace? for now i am only able to use options(error=recover), which is not giving me idea where exactly in the code i am once i am stopped on an error. -- View this

To compile vmkit on Ubuntu 12.04 64-bit machine, I followed the steps giving here <http://vmkit.llvm.org/get_started.html>[1]. but when I run ./configure I am getting following error- root at komal:/home/komal/Desktop/GSOC/vmkit/vmkit# ./configure >> -with-llvm-config-path=../llvm-3.3.src/configure >> --with-gnu-classpath-glibj=/usr/local/classpath/share/classpath/glibj.zip

I've run into a problem that I hope has an obvious solution. The sp package uses S4 classes and has a NAMESPACE, and when installed without package versions, runs OK, passes R CMD check, and so on. A user reported that he installed it --with-package-versions, and that from then on it would fail at first use of a class defined in the package. I've reconstructed the problem in a
