An organization may have projects using different versions of Python, R. Supporting different versions of Python and R in the same environment helps with upgrade planning.
Version 1 is "production use" and Version 2 is "testing upgrade".
This alleviates the worry about upgrading a package, because deployed code will remain stable and the new code can be tested in isolation.
Michael you will need to log a new idea. This request is asking that Python 1.1 and 1.2 be installed on the same computer... and allow easy switching between the two different versions. This allows testing to upgrade R or Python versions.
Could you elaborate on this, do you mean to allow Statistica to run R/Python nodes against the same environment, rather than depend on having the environment installed on each individual workstation/server? If so, I was about to submit the same idea.
