[LLVMdev] inserting a fucntion call at the end of basic bloc
hi all, i would like insert a fucntion call at the end of each basic bloc the fucntion i have defined and declared at the begining of the module ie i have written a pass derived from a module pass virtual bool runOnModule(Module & M){ // i declared the fucntion and defined it for (Module::iterator a = M.begin(), b = M.end(); a != b; for (Function::iterator i = a->begin(), e =

You can then link with an object file that defines it. This is

sampling
I want to sample from the ID. For each ID, i want to have 2 set of data. I try the sample() function but it didn't work. > x<-data.frame(id=c(1,1,1,2,2,2,2,3,3,3,4,4), v1=c(1:12), V2=c(12:23)) > x id v1 V2 1 1 1 12 2 1 2 13 3 1 3 14 4 2 4 15 5 2 5 16 6 2 6 17 7 2 7 18 8 3 8 19 9 3 9 20 10 3 10 21 11 4 11 22 12 4 12 23 -- View this message in

question with uniroot function
Dear all, I have the following problem with the uniroot function. I want to find roots for the fucntion "Fp2" which is defined as below. Fz <- function(z){0.8*pnorm(z)+p1*pnorm(z-u1)+(0.2-p1)*pnorm(z-u2)} Fp <- function(t){(1-Fz(abs(qnorm(1-(t/2)))))+(Fz(-abs(qnorm(1-(t/2)))))} Fp2 <- function(t) {Fp(t)-0.8*t/alpha} th <- uniroot(Fp2, lower =0, upper =1,

VaR-Monte carlo Simulation, Historic simulation, Variance-Covariance Simulation
Dear R helpers Suppose I have a portfolio of securities with exposure to Equity, Bonds and Forex (say $ 1000000 each). Is there any fucntion in R that will help me calculate Value at Risk (VaR) using Monte carlo Simulation , Historic simulation and Variance - Covariance Simulation. With regards Maithili

Reconstructing LD function
Dear all, in an LDA analysis with n groups n-1 LD functions result. Implicitly this defines an LD fucntion for the last group. Does there exist code already to explictly construct this LD function? Thanks, Stefan

matrix and a function - apply function

Newton-Raphson
Dear all, I want to solve a score function by using Newton-Raphson algorithm. Is there such a fucntion in R? I know there's one called optim, but it seems only doing minimizing or maximizing. Thanks, Jimmy

return the name of source.
Is there a fuction that will allow me to retrun the filename for a script from within that script. fir instance If I have a script "myscript.r": FileName<-unknown.fucntion() print(FileName) and run it source("myscript.r") will return "myscript.r" Thanks Nevil Amos [[alternative HTML version deleted]]

fft question
Hi! I am using the fft() function the base package to transform some 1d signal. If I use this standar fucntion I get a very huge first fourier coeficient. I think this dues to the handling of the borders of the signal. Usually in fft especially in image processing the signal is simulated to be continuous by adding the signal several times periodically. My question is, is there some function

[LLVMdev] Attribute to mark that function only access memory through it's arguments
Hi, Currently in AliasAnalysis we can model ModRef behaviour for functions which only access memory through their pointer arguments. However we can't express this propery as a function attribute. For example, for intrinsics we can specify ReadWriteArgMem or ReadArgMem attributes in tablegen definitions. But due to the lack of the related function attributes on the llvm ir level, this

using list to pass argument to function
Hi, I am trying to apply *sapply* to functions within functions within functions to do a Monte Carlo experiment: take Y sample of size X based on cell probabilities (using Brian Ripley's suggestion for drawing from contingency tables), for each calculate a vector of statistics, calculate bootstrap std errs with R replications and their means and SD. Store results in a matrix for further

how to modify an R built-in function?
Hello R experts! Last week I run in to a lot a problems triyng to fit an ARIMA model to a time series. The problem is that the internal process of the arima function call function "optim" to estimate the model parameters, so far so good... but my data presents a problem with the default method "BFGS" of the optim function, the output error looks like this: Error en
