Hi, I have a nicely printed table of results generated by R's > print(myresult) where myresult is a "data frame". I am trying to put this table into a powerpoint slide for presentation without re-typing and re-formating, i.e., present it as it is in the R window.

Is there a way to have the mongrel_cluster prefix option be case insensitive? Right now if I have a cluster with prefix: /myapp in the mongrel_cluster.yml file, it works fine when someone types in http://mysites.com/myapp. But, if someone types into their browser: http://mysites.com/MyApp They get a 404. Can the prefix be case-insensitive? -- Sean

Hi Ezra, Thanks for the great work on BackgrounDRb. I have come across a couple of problems. 1. I wanted to define a simple class in the worker file to wrap up and pass back some data to my controller.

Hey everyone, I know that I can call 'R' from other scripts, and that I can make command calls from 'R' (e.g., using system() ). But how can I get 'R' to RETURN values to the script that called it. E.g., I would like to be able to do something like the following (as a simpler example) from a bash script: #!/bin/bash myTest=echo /usr/local/bin/R --no-restore
