Hello, The quick version of my question is how can I extract a matrix instead of a vector using tapply()? I would like to be able to access both the results of tapply() and also the index variables. In case further explanation would help: I am analyzing a large (3million rows x 9 columns) spatial/temporal dataset and am attempting to calculate the number of unique years containing any data within each geographic area (10 degree cells in this case). I can do this, but I also want to extract a subset vector of the index variable (area). My script to calculate the nu...

...ers of different kinds. Bacula is relatively easy to use and very efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files.

Below are the loop and the head of the dataframe I am workin...

However, any additions to these records are added to the database through an external script so the aaf activerecord hooks will not catch any updates. Since new records are only added rarely, I figured I could just add the new records manually in ferret from some type of script. I...

I'm working on bring up a new mail server to replace our current one. Our current mail server is running dovecot 1.1.16, with postfix using mbox format. User inboxes are stored locally on the mail server and all other mail folders in users home directory under mail which is NFS mounted on the mail server. For our new mail server I'm looking to switch to the Maildir format. Some
