[Orgmode] [babel] noweb for :sessions?

[Thomas S. Dye]

Aloha all,

Is it possible to define frequently used code snippets in a generic way so they can be used in different sessions?

Something like this is what I have in mind:

#+srcname: r-connect

#+begin_src R :exports none :session any

library(rMySQL)

con <- dbConnect(MySQL(), user="user_name", password="password", 

                     dbname="db_name", host="host_name")

#+end_src

#+srcname: r-query

#+begin_src R :session session-1 

# <<r-connect>>

res <- dbGetQuery(con, "select * from table_name where 1")

#+end_src
