problem with "transform" and "get" functions
Hello, I'm having a problem using the "transform" and "get" functions. I'm probably making a dumb mistake, and I need help! I start by making a small simulated dataset. I save the names of the variables in "var.names." Without getting into the details of it, I have to create a custom function to perform some statistics. As part of this, I need to sequentially

environment variables in kickstart
I have been looking for environment variables for the %post section of kickstart. Namely if I start my kickstart command with "linux ks=http://serverip/ks.cfg" is there an environment variable that has serverip that I can use in the %post section? Also is there a way to pass a command line argument to the %post section when running kickstart command as the above

R and condor
Hello, I would be extremely grateful if anyone is able to provide any (rather obscure) advice on using R with Condor. I think I'm following Xianhong Xie's instructions (R News 5(2) 13-15) correctly, but my job just stays held in the queue (for days / months). I've checked condor_status to make sure there are plenty of machines available, but can't see any way to attack the

Vmware - Slightly off topic
Hi All, What is the correct way to provide a CentOS 7 - WMware image for ESX ? As an amateur to VMware - I thought - great I can get VMplayer and ESX should be able to import my image... Wrong... I even went through the trouble of "converting" to VMWare workstation and thinking ESX could import that - Apparently still Wrong... I cannot for the life of me understand how one product

R-alpha: "invisible" (yet again): a more problematic bug[let]
