Consistency with Rpy 1 and NumPy packages and tools, e.g. linear_regression

[blankenberg]

These tools and dependency chains are broken. But will work if you have numpy 1.7 available locally. Detailed analysis follows.

Rpy requires NumPy, but the current version of rpy 1.0.3 in the toolshed (https://toolshed.g2.bx.psu.edu/repos/devteam/package_rpy_1_0_3/file/82170c94ca7c/tool_dependencies.xml https://toolshed.g2.bx.psu.edu/view/devteam/package_rpy_1_0_3/82170c94ca7c) does not have a repository dependency defined.

However, the current version in github, https://github.com/galaxyproject/tools-devteam/blob/fbc219afb27b57b7a7aabbf2936439273753664e/packages/package_rpy_1_0_3/tool_dependencies.xml, has a dependency on numpy 1.9, added in fbc219afb27b57b7a7aabbf2936439273753664e.

But I don't think we can or should 'just update' this package in the toolshed, due to inconsistencies when digging into tools.

The linear_regression tool (https://github.com/galaxyproject/tools-devteam/tree/master/tools/linear_regression https://toolshed.g2.bx.psu.edu/view/devteam/linear_regression/cf431604ec3e) has dependencies on rpy 1.0.3, R 2.11.0, and numpy 1.7.

This causes an error with linear_regression (and possibly other tools), when Rpy is built against NumPy 1.9, but given NumPy 1.7:

RuntimeError: module compiled against API version 9 but this version of numpy is 7

I was able to hack the Rpy 1.0.3 package locally to get these tools to work, with this:

and then uninstalling/reinstalling rpy 1.0.3.

This was the path of least resistance given the current state of the packages in the toolshed (rpy not requiring numpy).

However, the correct fix is most likely to have rpy require numpy (like in current github-only copy, numpy version is up for debate), and simultaneously update any tools using rpy to not manually require their own version of numpy, thereby getting the version inherited through the rpy dependency chain.
