Hi there, I have a spreadsheet in excel which consists of first column of dates and then subsequent columns that refer to prices of different securities on those dates. (the first row contains each series name) I saved the excel file as type csv and then imported to excel using prices=read.csv(file="C:/Documents and Settings/Hugh/My Documents/PhD/Option prices.csv",header = TRUE, sep

m0<-epxression((4*theta1*theta2-theta3^2)/(2*x*theta3^2)-0.5*theta1*x) params<-all.vars(m0) this reads all the params from m0 so theta1,2 and 3 correct? params<-params[-which(params=="x")] checks which params are multiplied by x? np<-length(params) for(i in 1:6){ esp<-get(sprintf("m%d",i-1))

Hi there, What is the best way to get a time series of daily stock price observations into R (from excel). The time series are daily but there are spaces for w/e's and holidays etc. So I am not sure a ts object will be suitable but I am not sure what I should use? What ever package you recemmned i need to be able to run a corrolelagram. Thanks Hugh -- View this message in context:

Hi there, I ran the following code: vols=read.csv(file="C:/Documents and Settings/Hugh/My Documents/PhD/Swaption vols.csv" , header=TRUE, sep=",") X<-ts(vols[,2]) #X dcOU<-function(x,t,x0,theta,log=FALSE){ Ex<-theta[1]/theta[2]+(x0-theta[1]/theta[2])*exp(-theta[2]*t) Vx<-theta[3]^2*(1-exp(-2*theta[2]*t))/(2*theta[2]) dnorm(x,mean=Ex,sd=sqrt(Vx),log=log) }

I am sorry for the long *involved* post, however we are at wits end and advice would be greatly appreciated. Background: We have three servers in this example. Two of the servers (we will call Server A & B) each have a 2.7T raid 5 array that is mirrored with DRBD and monitored for failover with Heartbeat. NFS is running and exporting the array on Heartbeats virtual IP. "Server C"

Thanks. I was worried about the assembler invocation but it looks like you solved that problem. Smooth build on my pbook (G4, 10.2.8, gcc-3.3, ac-2.59, am-1.6.3). Only problem was lack of check for docbook-to-man; my patch is attachments 1-2. Not so smooth on my imac (G3, 10.2.8, gcc-3.3, ac-2.52, am-1.6.1; that's what came with the last 10.2-compatible dev tools). First problem: typo in

Chris, nice segue to Swift ! :-), but... The question is what should LLVM do with UB in general, saying that we are going to change one specific idiom from undefined to defined glosses over the real question: why should we ever optimize / delete any UB at all ? This “depressing and faintly terrifying thing” as you call it, should be viewed not as an opportunity for optimization, but

While y is lower triangualr 0's with the remaining cells all ones. I really don't understand how this deceptively simple looking piece of

Hi R-Core, i am using nnet and DEoptim, Xcc=matrix(rnorm(100,0.5,0.08),50,2) Ycr=matrix(rnorm(50,0.2,0.05),50,1) pred_regm1 <- function(A) { A1=A[1] A2=A[2] A3=A[3] regm1 <- nnet(Xcc,Ycr,entropy=T,size=A1,decay=A2,maxit=2000,trace=F,Hess=T,rang=A3,skip=T) dif=sum((predict(regm1,Xcc)-Ycr)^2) return(dif) } somar=DEoptim(pred_regm1,c(1,0.00001,0.01), c(25,0.999,0.95),

This must be possible; not sure how to do it yet. :) After facing the thought of going through my cd collection for a 3rd time for re-encoding, it occurred to me that I should just flac the whole CD and add a cue sheet, and then back up to DVDs. That way -next- time I need to re-encode to any format, I can handle ~1/20th the discs, compared to my whole cd collection. :) Wondering if

Hi there, I am reletively new user I only dowloaded is about a week ago. I was getting along fine but last night I tried to selected save workspace. Since then R will not work!!!! And I really really need it. There are two eror massages: The first if a pop up box is "Fatal error: unable to resolve data in .RData." The second is a message in the GUI: "Error in

Hello, I'm working with the gam function and due to the amount of data I am working with it is taking a long time to run. I looked at the tips to get it to run faster, but none have acceptable side effects. That is the real problem. I have accepted that gam will run a long time. I will be running gam many times for many different models. To make gam useable I am looking at splitting the work
