Hi - 
I tried to install the package charts but it failed on the dependency charts_r_packages with this error:

File "/home/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/install_manager.py", line 139, in install_and_build_package_via_fabric tool_dependency = self.install_and_build_package( tool_shed_repository, tool_dependency, actions_dict ) File "/home/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/install_manager.py", line 97, in install_and_build_package initial_download=True ) File "/home/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/recipe_manager.py", line 32, in execute_step initial_download=initial_download ) File "/home/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/step_handler.py", line 1238, in execute_step self.url_download( work_dir, filename, url, extract=False ) File "/home/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/step_handler.py", line 183, in url_download raise Exception( err_msg ) Error downloading from URL http://cran.r-project.org/src/contrib/Matrix_1.1-4.tar.gz: HTTP Error 404: Not FoundInstalled tool dependencies: charts_r_packages

It looks like matrix is now at version: Matrix_1.1-5.tar.gz
