jpeg() creating empty files with qplot() in a loop
Hello all,
I'm stuck with a strange issue with writing jpegs of plots to a folder
in a loop.
This works:
for (step in 1:length(steps)) {
jpeg(filename=paste("frame_",sprintf("%05d",step),".jpg",sep=""))
plot(steps[[step]])
dev.off()
}
But if I use qplot to generate the plot (which is my aim):
for (step in 1:length(steps)) {
jpeg(filename=paste("frame_",sprintf("%05d",step),".jpg",sep="...

Need help on changing a table
Hi all:
Im kind of new on R and I need help changing a table. The thing is, i read a
file on R using the read.table command and the table looks like this:

Legalese. What is stride?
Hello all.
I've been playing around with theora since it first entered CVS, and I
like what I'm seeing. Today I've been fixing xine's theoraplugin to
understand theora_info.frame_{width,height} and
theora_info.offset_{x,y}. I only got it working after some experimenting
and basically copying the code from player_example. A few questions
related to this:
1. What are the legal requirement in regard to copying code from your
BSD-style license to xine, which is under the GPL. I...

Pls package
Hi,
I have managed to format my data into a single datframe consisting of two AsIs response and predictor dataframes in order to supply the plsr command of the pls package for principal components analysis.
When I execute the command, however, I get this error:

Hello all,
I have a data file table.txt which i have attached. I am trying to pass the
columns as arguments to a function "totnorm" where i am displaying a total
normalization plot. The function is given below:

[RFC PATCH v2] Encode optimize using libNe10
Changes from RFC PATCH v1:
- passing arch parameter explicitly
- reduced stack usage by ~3.5K by using scaled NE10 fft version
- moved all optimization array functions to arm_celt_map.c
- Other cleanups pointed out by Timothy
Phil,
As you mentioned earlier, could you please address all
compile and linker errors/warnings coming out of Ne10 library?
You can find my working Ne10 repo at [1]

[RFC PATCHv3] Encode optimize using libNe10
Changes from RFC PATCH v2
- fixed compile issue when just compiling for --enable-intrinsics
for ARMv7 without NE10
- Notes for NE10:
- All compile/link warnings are now in upstream NE10
- Only patch pending upstream in NE10 is the one that
needs to add -funsafe-math-optimizations for ARMv7
targets.
- Phil Wang @ ARM is working on getting this fixed.
- Note that even without

[RFC PATCH v1 0/4] Enable aarch64 intrinsics/Ne10
Hi All,
Since I continue to base my work on top of Jonathan's patch,
and my previous Ne10 fft/ifft/mdct_forward/backward patches,
I thought it would be better to just post all new patches
as a patch series. Please let me know if anyone disagrees
with this approach.

[RFC PATCH v1 0/5] aarch64: celt_pitch_xcorr: Fixed point series
Hi Timothy,
As I mentioned earlier [1], I now fixed compile issues
with fixed point and resubmitting the patch.
I also have new patch that does intrinsics optimizations
for celt_pitch_xcorr targetting aarch64.
You can find my latest work-in-progress branch at [2]
For reference, you can use the Ne10 pre-built libraries
at [3]
Note that I am working with Phil at ARM to get my patch at [4]

Rest of patches are same as in [1]
For reference, latest wip code for opus is at [2]
Still working with NE10 team at ARM to get corner cases of

when issue in NE10 gets fixed.

[RFC PATCH v1 0/8] Ne10 fft fixed and previous
Hello Timothy / Jean-Marc / opus-dev,
This patch series is follow up on work I posted on [1].
In addition to what was posted on [1], this patch series mainly
integrates Fixed point FFT implementations in NE10 library into opus.
You can view my opus wip code at [2].
Note that while I found some issues both with the NE10 library(fixed fft)
and with Linaro toolchain (armv8 intrinsics), the work
