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?

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

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), Timo Stolz

Hello all, I am an R novice and I have a simple question and hope somebody can help me out. I need to place several labels in a plot, this labels are some kind of text and also some objects (which come from some more complicated R calculations). In one of this labels I'd like to place a superscript, however I cannot find a way to place both the expression and the object in the same

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:

Hi I am trying to carry out some maximum likelihood estimation and I'm not making much headway, and I'm hoping that someone will be able to point me in the right direction. I am modelling mortality statistics. One way to do this is to model the mortality rate (or, more accurately, log of the mortality rate, log_m) as (say) a constant plus a proportion of age, plus time, so: r_1 <-

Dear all, Is there any method in R to find all possible nonnegative integer solutions to the linear equation with unit coefficients as follow: X1+X2+...+Xk=N Thank you, Amin Zollanvari

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: > vmovdqu32 zmm0, zmmword ptr [rax + c+401280] ;load b[401280] in > zmm0 > > vpaddd zmm1, zmm1, zmmword ptr [rax + b+401344] > ; zmm1<-zmm1+b[401344] The KNL can only

Hi, I am trying to figure how to use dlm with constant terms (possibly time-dependent) added to both equations y_t = c_t + F_t\theta_t + v_t \theta_t = d_t + G_t\theta_{t-1} + w_t, in the way that S-PLUS Finmetrics does? Is there any straightforward way to transform the above to the default setup? Thanks, Tsvetan -------------------------------------------------------- NOTICE: If received in

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

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

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: May 10 03:35:58 localhost pure-ftpd: (tool at

Sorry, I can't reproduce the example below even on the same machine. However, the following example produces the same error as NULL values in prior examples: > setClass("FOOCLASS", +????????? representation("list") + ) > ma = new("FOOCLASS", list(M=matrix(rnorm(300), 30,10))) > isS4(ma) [1] TRUE > data.frame(a=1:3) == ma Error in

Hi Guys, After some moths the server has been running in SELinux Permesive mode ... Some avc: denied messages has been recored ... I thought it was time to go to the next step and set SELinux Enforcing mode in the server ... it is a mail(postfix+cyrus+sasl), web, snmp with mrtg, squid sever with a local TLS configured for webmail access ... I took a look to the Deployment Guide about how to do

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 -- Alan Spearot Department of Economics

I haven't used r in quite a while but would like to get back into it. I have a problem that I would like to solve with r. I have some multinomial data that looks to follow an asymmetric sigmoidal growth pattern. Solving a multinomial gompertz partial differential equation in r is what I’m after. Would anyone be able to provide me the code and packages to do something like this? Regards,

I am experimenting with exporting pointers to some of the functions in deSolve so that other packages may import them, using the 'R_RegisterCCallable' mechanism. I have added a header file and some other C code in inst/include of the deSolve source package that need to be accessible to other packages. I have a site-library set up in Rprofile.site where all installed packages go, and as

Dear list The deSolve package allows you to specify the model code in C or Fortran. Thanks to the excellent vignette this works fine. However I have not yet managed to use forcing functions in C code. In pure R code this works very well with approxfun() specified outside the model: ############################################### #Model lvml <- function(t, x, parms) {
