Writing a workable function
After searching in R- Introduction, FAQ, help... I don't understand
this:
I write a function in a file (.R):
tt <- function(mc) { date()
mc<-read.csv2("machines.txt",na.strings="")
date()
}
I source it in R and I type tt(). The answer is
> tt()
[1] "Mon Aug 14 11:18:25 2000"
>
The instructions following the first "date()" are ignored. Why?

Patch cleaning up Opus x86 intrinsics configury
The attached patch cleans up Opus's x86 intrinsics configury.
It:
* Makes ?enable-intrinsics work with clang and other non-GCC compilers
* Enables RTCD for the floating-point-mode SSE code in Celt.
* Disables use of RTCD in cases where the compiler targets an instruction set by default.
* Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in

AVX Optimizations
Yes,
Thank you. I'll follow up with the AVX code and tests for pitch code.

[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]

[RFC PATCH v2]: Ne10 fft fixed and previous 0/8]
Hi All,
As per Timothy's suggestion, disabling mdct_forward
for fixed point. Only effects
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
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
mdct_forward. Will update with another patch
when issue in NE10 gets fixed.

[RFC V3 0/8] Ne10 fft fixed and previous
Hi All,
Changes from RFC v2 [1]
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
- Overflow issue fixed by Phil at ARM. Ne10 wip at [2]. Should be upstream soon.
- So, re-enabled using fixed fft for mdct_forward which was disabled in RFCv2
armv7,armv8: Optimize fixed point fft using NE10 library
- Thanks to Jonathan Lennox, fixed some build fixes on iOS and some copy-paste errors
Rest

[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

[newbie] aggregating table() results and simplifying code with loop
...g table() results and at
writing a loop (if useful)
My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one
representing a point in the space of which we know the land cover over
10 years (column y01 to y10).
I need to analyse it with a temporal sliding window of 5 years (y01 to
y05, y02 to y06 and so forth)
For each period I'm looking for specific sequences (e.g., Maize,
-noMaize, -noMaize, -noMaize, -noMaize) to calculate the "return time"
of principal land covers: barley (2BC), colza (2Co), maize (2Ma), etc.
I define the "return time" as the presence of a...
