I am running into problems calling the library function nlme from within another function. Basically,the following function (with v a list containing data and initialization values) > testfunc function(dat=v) { test<-nlsList(result~a+(b-a)/(1+(conc/(c+z*cdiff))^d) |rep,start=dat$init,data=dat$mixeddat) return(nlme(test,random=b~1)) } produces the error message Error in eval(expr, envir,

Hi there, I want to generate a large amount of functions, say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x)) where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2, log(x), log(1+x) .. and so on. Any suggestions on how to do this efficiently? thanks a lot. x.w

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 =

Dear everyone, I'm doing some simulations which involves bootstrapping (using functions written in c loaded with R's dyn.load() function) and maximising the likelihood function with R's nlm() function. I used to run my code in S-plus but because I frequently ran out of memory (because of S-plus' silly memory management), I decided to try porting my code to R. In R (on a linux

Hello! I have the problem that in my function the passed variable is not used, but the variable name of the dataframe itself?- difficult to explain, but an easy example: TestFunc<-function(df, group) { ??? print(names(subset(df, select=group))) } df1<-data.frame(group="G1", visit="V1", value=0.9) TestFunc(df1, c("group", "visit")) Result: [1]

Hi Nabila, > My problem is how to call a method > suppose this fucntion > void A(int x) > { > x=x+1; > > } > > should i define this function and declare it at the beginig of the module and > create for it a basic bloc? you can just declare the function (i.e. no need to give it a body), and call it. You can then link with an object file that defines it. This is

I have defined the fucntion in another object file and linked it to the in fact the fucntion is : void consume(int , int * ); std::vector<Value*> int32_16_params; int32_16_params.push_back(inValue);//inValue is ConstantInt* inValue int32_16_params.push_back(gvar_int32_y); CallInst* int32_16 = CallInst::Create(func_consume, int32_16_params.begin(), int32_16_params.end(), "",

I''m trying to attach effects to elements in my onload handler and my lack of Javascript-fu is showing... I want to call the effect from the onclick handler of an anchor inside the div I want the effect to apply to. Here''s what I''m trying to do: function doOnLoad() { var filters = document.getElementsByName(''filter''); for

Hi Nabila, > i would like insert a fucntion call at the end of each basic bloc you can't, because only terminators are allowed at the end of a basic block.

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,

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

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

Hi I have this function and this matrix: function(x,y) x+y/x m<-matrix(c(1,2,4,2,10,8),3,2) > m [,1] [,2] [1,] 1 2 [2,] 2 10 [3,] 4 8 each row represent a point (x,y) in a chart and I want via my fucntion to calculate the image in order to get this results: for point (1,2) I would get 1+2/1 = 3 for point (2,10) I would get 2+10/2 = 7 for point (4,8) I would get

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

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]]

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

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
