Event-triggered change in value with a time-delay
Hello,
I am solving a set of ODEs using deSolve and have run into a problem I
would appreciate some advice on. One of the parameters (m) in the ODEs
changes between two states when one of the variables (D) crosses a
threshold (D_T) for the first time in either direction. Additionally, when
the variable crosses the threshold (either by increasing or decreasing),
there is a time delay (delay)

Register Allocation and Scheduling Issues
Hello,
I have defined 8 registers in registerinfo.td file in the following order:
R_0, R_1, R_2, R_3, R_4, R_5, R_6, R_7
But the generated assembly code only uses 2 registers. How to enable it to
use all 8? Also can i control the ordering like after R_0 can i use R_5
without changes in registerinfo.td?
What changes are required here? either in scheduling or register allocation
phases?

Potential cross-platform package building issue
I am using 32-bit R 3.1.2 on Windows 7.
I recently conducted an `R CMD check --as-cran` on a recently-developed
package and received only the 'New submission' note. Research on
StackOverflow and on R-devel suggested this could be ignored. I also used
devtools::build_win() and received no notes or warnings, other than the one
mentioned previously. Lastly, I conducted an `R CMD check` with

strange system outage
I have a CentOS 7 system that I run a home grown python daemon on. I
run this same daemon on many other systems without any incident. On
this one system the daemon seems to die or be killed every day around
3:30am. There is nothing it its log or any system logs that tell me
why it dies. However in /var/log/messages every day I see something
like this:

Matrix/Vector manipulation
Hi guys,
Have the following problem computing vectors with pure vector algebra and end up reverting to recursion or for-looping.
Function my_cumsum calculates a weighted average (W) of ratios (R), but only up to the given size/volume (v). Now I recurse into the vector (from left to right) with what you have left from the difference of volume minus current weight, and stop when the difference is

AVX Scheduling and Parallelism
Hi, Zvi,
I agree. In the context of targeting the KNL, however, I'm a bit
concerned about the addressing, and specifically, the size of the
resulting encoding:

AVX Scheduling and Parallelism
Hi Ahmed,
>From what can be seen in the code snippet you provided, the reuse of XMM0 and XMM1 across loop-unroll instances does not inhibit instruction-level parallelism.
Modern X86 processors use register renaming that can eliminate the dependencies in the instruction stream. In the example you provided, the processor should be able to identify the 2-vloads + vadd + vstore sequences as

significance test for difference of two correlations
Dear R users,
how can I test, whether two correlations differ significantly. (I want to prove, that variables are correlated differently, depending on the group a person is in.)
Greetings from Freiburg im Breisgau (Germany),

R-devel Digest, Vol 181, Issue 22
Thanks.
I am fully aware of what aggregate() returnes, and I can post-process this into the form I want ? if the names are available.
But for foo, the returned object is both different in structure and loses the name altogether:
foo <- function(x) { c(mean = base::mean(x)) }
str(aggregate(iris$Sepal.Length, by = list(iris$Species), FUN = foo))
## 'data.frame': 3 obs. of 2 variables:

Is there any method in R to find all possible nonnegative integer
solutions to the linear equation with unit coefficients as follow:

Creating mixed line and point graphs with xyplot
Hi
Well, I think the title says it all!? I've looked through the documentation but I can't find a way of doing this.? The situation is that I have 4 series, say a, b, c and d.? Series a and c are plotted on the lh y axis, series b and d are plotted on the rh (secondary) y axis.? I've worked out how to do this.
However, I need to plot series a and b a points (symbols only, no line),

Heteroskedasticity in Tobit models
Hello,
I've had no luck finding an R package that has the ability to estimate a
Tobit model allowing for heteroskedasticity (multiplicative, for example).
Am I missing something in survReg? Is there another package that I'm
unaware of? Is there an add-on package that will test for
heteroskedasticity?
Thanks for your help.
Cheers,
Alan Spearot

2.2.8 doesn't compile on Tru64-5.1
HI,
I've successfully compile 2.2.8 on Solaris (6,7,8) and Linux. However on
Tru64-5.1 I get the following during the make:
Compiling smbd/dfree.c
Compiling smbd/dir.c
smbd/dir.c:649:70: macro "stat" passed 3 arguments, but takes just 2
smbd/dir.c:716:13: macro "stat" passed 3 arguments, but takes just 2
make: *** [smbd/dir.o] Error 1
Any ideas?
