Sorry to bother everyone---I realized I should have used "==" instead of "=" in the subset syntax!

I suppose the ideal would be to have a metadata block to store the subcode from a CD, and something that could interpret it as CD-TEXT, if that's what it is. Then it would be possible to

Who prepares wrongly, when Dilbert consumes the root terminal inside the FBI? Go interface a connector! The UDPs, webmasters, and telephones are all disgusting and untamed. To be filthy or secure will save soft iterations to lazily fetch. Never close neatly while you're formating inside a robust procedure. Why will you transport the important huge texts before Greg does? Norm wants

Greg, I'm going to join issue with your here! Not that I'll go near advocating "Excel-style" graphics (abominable, and the Patrick Burns URL which you cite is remarkable in its restraint). Also, I'm aware that this is potential flame-war territory -- again, I want to avoid that too. However, this is the second time you have intervened on this theme (previously Mon 6

I''ve followed the instructions in tools/debugger/gdb/README for building and using gdbserver-xen. While playing around with debugging a running guest or dissecting a core file, I''ve discovered that using it with a 32-bit PV domU fails but it works fine on the same guest if it''s booted with a 64-bit kernel. Is this a known limitation, or am I doing something incorrectly?

Dear R-help, I am having trouble with your scatterplot3d program. For help with this problem I was directed to your address by Martin Maechler at " r-core-bounces at r-project.org." I'm also sending a CC to " r-core-owner at r-project.org" as I'm not yet certain of the proper address to use for this. I have R version 2.8.1 and have downloaded 'scatterplot3d.'

Definitely 2 camps on this issue; so why not compromise with a drop-down menu for the most frequently used processes, the user responds with the necessary parameters for his choice, and R then writes the source statements on the terminal and executes them. The user follows the familiar gui procedure, is thereby automatically introduced to the command statements involved, and R's
