Hi,
I have a problem with R, after an update:
this piece of code:
cat("creating resolver data frame\n");
dfG<-cbind(dfG,2^(RGN$G))
dfR<-cbind(dfR,2^(RGN$R))
suddenly, creates values to inf.
Is the syntax changed for the ^ symbol in the latest R downloadable version?
Kind regards, wilfred

What are RGN$G and RGN$R? Consider the following: > .Machine$double.xmax [1] 1.797693e+308 > log(.Machine$double.xmax, base=2) [1] 1024 > 2^(log(.Machine$double.xmax, base=2)-1) [1] 8.988466e+307 > 2^log(.Machine$double.xmax, base=2) [1] Inf If you want something different from this, PLEASE do read the posting guide!

Dear Sir/Madam I would be pleased if anybody can help me. I'm using linear mixed model (lme) function.I'm doing some simulation in my research and need to be assigned variance components values during of my program. Specifically, when I use lme function, I can get some information by use summary() and I can assign some valuse like variance of fixed parameters and variance of random error term by using for example varFix and sigma.But I don't know how I can assign for variance of random effect. I know in SPLUS we have command var.ran, how about R ? Thanks alot. M.Torabi
