Patch that fixes distortions during static scenes
Here is a patch that fixes distortions that appear during scenes with no
motion. Tbe problem was that UpdateFrame() was not being called when a
MotionScore of 0 was computed. Since UpdateFrame() was not called the buffer
returned by theora_encode_packetout() would be the same buffer that was output
for the last frame that had a non-zero MotionScore. This is obviously incorrect
behavior. I've

Fix a bug that causes the encoder to spend way to many bits on keyframes
Here is a fix that prevents the encoder from spending too many bits on
keyframes. The main problem is that the old code computes the target keyframe
bitrate incorrectly. This causes the code that computes the Q for the frame to
think that it has tons of bits to spend. It selects a high Q value for the
keyframe. Since so many bits were spend on the keyframe the the inter-frames
have to use a much

Thusnelda - Floating point exception in encoder_toplevel.c:209
Hi all,
I've been hitting the odd floating point exception errors using the
new alpha encoders. They're encoding a live stream so I can't reproduce
the crash on demand, and it might only happen once every few days so
it's been fun trying to get a backtrace. The crash happens in a fairly
scary block of code, I wouldn't have a clue where to begin trying to fix it!

Small memory leak...
Hi all.
In lib\encoder_toplevel.c , row 1123-1128:

memcpy(op->packet, oggpack_get_buffer(opb), oggpack_bytes(opb));

legend with mixed boxes and lines (not both)
Hi,
I seem to be unable to get a mixed legend that has lines *or* polygons
(not both). For example:
ppi <- seq(0,2*pi,length.out=21)[-21]
frame()
plot.window(ylim=c(-5,5),xlim=c(-5,5),asp=1)
polygon(cos(ppi)*4+rnorm(20,sd=.2),sin(ppi)*4+rnorm(20,sd=.2),
col="green",border=FALSE)
polygon(cos(ppi)*2+rnorm(20,sd=.1),sin(ppi)*2+rnorm(20,sd=.1),
col="blue",border=FALSE)

dput/dget when a data frame has 2 rows (PR#9627)

I have a problem with R!!
Dear all
i?m working with a program i?ve made in R (using functions that others
created)
to run my program i need a sample. if i generate the sample using for
example, rnorm(n, mu, sigma) i have no problem
but if i obtain a sample from a column in excel and i copy it, the program
says that there is a mistake: it says "Error en `[.data.frame`(data,
indices) : undefined columns

Interesting observation with network event notification and batching
Hi all
I''m hacking on a netback trying to identify whether TLB flushes causes
heavy performance penalty on Tx path. The hack is quite nasty (you would
not want to know, trust me).
Basically what is doesn''t is, 1) alter network protocol to pass along
mfns instead of grant references, 2) when the backend sees a new mfn,
map it RO and cache it in its own address space.

problems with assign
Hello.
I have n files in a directory: file1, ..., filen.
I read them with the following commands:
list=scan(file="list",what=list(nom=""))
# in the file list, I have all the filenames.
n=length(list[[1]])
for (i in 1:n){
aux <- paste("p",i,sep="")
assign(aux, as.matrix(read.table(list[[1]][i])))
}
R creates the matrices p1,p2,...,pn.

High resolution plots
Is there any possibility to get high resolution plots in a windows xp
system?
I tried it with the device function png(filename =
"c:/r/highresplot%d.png",pointsize=12, res=900)
but when I try to set: width = 480, height = 480 or pointsize = 12,
the text is not scaled in the same way as the plots.

Identification Header
Hi,
While creating identification header in the function *
theora_encode_heade*r in *encoder_toplevel.c*, it assigns bits not mentioned
in the current theora spec released on Octomber 29, 2007 (page 40 &41).
But this implementation in function* theora_encode_heade*r is correct
according to the *Figure 6.2 (page 42)*. But not according to the *table
