So in R rather than evaluating the block using the R command line, an *R* buffer will be created and evaluation will take place in that buffer. This allows the persistence of environment between different source-code blocks. So it would be possible to create a variable in one source-code block, and reference it in another if both blocks have the same session header argument. Adding a string after :session will name that session, while just the session header will use the default session -- i.e. *R* for r code, or *ruby* for ruby, etc...
