I'm an R newbie but recently discovered the ggplot2 and reshape packages which seem incredibly useful and much easier to use for a beginner. Using the data from the IMDB, I'm trying to see how the average movie rating varies by year.

Hello everyone: Over the past few years I have been a happy samba user, running samba on Redhat / FC platforms. Recently I upgraded hardware, and Samba hasn't been performing well at all.. which makes me sad :-( The new hardware is Asus P5B board with a dual-core intel processor. This board has an onboard Realtek RTL8111/8168B gigabit ethernet controller, which was a hassle to setup.

Text is really small and legend boxes are huge in this plot when saved to .png with ggsave. Plot is correct (i.e. looks the same as the screen) when saved with dev.print. Saving to .pdf with ggsave give the correct output. I'm a noob at ggplot2 so this may be user error rather than a bug. However the interface to ggsave seems simple enough to exclude many possibilities for screwing this up

Looking at the API, I see that there are functions for this in swfdec_sprite_movie.h. But I don't see how I can get to those functions starting from a swfdec_player. Second, there are some movies that are collections of

Hi, I've been using PxeLinux to boot our Debian kernel successfully for some time now. I recently increased the size of the ramdisk from about 484 MBs to 517 MBs and encountered the following error during bootup: --- RAMDISK: Compressed image found at block 0 Freeing initrd memory: 105519k EXT3-fs: Magic mismatch, very weird! cramfs: wrong magic sh-2021: reiserfs_read_super: can not find

The error occurred while evaluating nil.accepts): The show method has the same respond_to block but doesn''t error out. If I take the respond_to block out of the index method, it works.

I'm playing the "Honey" movie (both Honey-small and Honey-large) and I notice significant slowdown during periods of lots of motion (when the camera shakes, when the first man hops into bed, when people turn around and approach the camera, etc.). The audio plays smoothly all the time but when there is a lot of motion, the picture freezes and resumes when there's less motion.
