Dear Friends. I found something very puzzling with constOptim(). When I change the parameters for ConstrOptim, the error messages do not seem to be consistent with each other: > constrOptim(c(0.5,0.3,0.5), f=fit.error, gr=fit.error.grr, ui=ui,ci=ci) Error in constrOptim(c(0.5, 0.3, 0.5), f = fit.error, gr = fit.error.grr, : initial value not feasible > constrOptim(c(0.5,0.9,0.5), f=fit.error, gr=fit.error....

Dear friends. I use ConstrOptim( ) and got error message "initial value not available". My understanding of "initial value not available" is that one of the following 3 cases happens: 1.The objective function is not well defined at the point of the initial value. 2. The differentiation of the objective function is not well defined...

...uld not use AOV to perform an anova on my large data set, I'm now trying to code the analysis "by hand" so to speak. However, as demonstrated below, when comparing my attempt to aov() using a smaller data set, I seem to betray some sort of misunderstanding when I try to compute SSerr for the first interaction. Obviously I have missed something and although I have looked around for the explicit SSerr formulas for this design (my work thus far was extrapolated from understanding of a 2-way design), I can't seem to find any. Any help would be much obliged. N = 20 l...

I have what I'm sure will turn out to be straightforward. I want to store the results of a loop for some operations from a patterned vector. For example, the following doesn't give what I would hope for ss <- c(2,3,9) results <- numeric(length(ss)) for (i in seq(along=ss)){ results[i] <- i + 1 } The following does give what I expect, but creates a vector of length 9. ss <- c(2,3,9) results <- numeric(length(ss)) for (i in ss){ results[i] <- i + 1 } What I am hoping fo...

...thing works fine except the plot only puts y-axis tick marks on cells in column one and x-axis tick marks on cells in row three. I would like tick marks on both the x and y axix of all 9 plots in my array. I am generating plots using the following two functions three.by.three.plot <- function(ss) { par(mfrow=c(3,3)) sub.plot(ss,1.5,0.02) sub.plot(ss,1.5,0.04) etc par(mfrow=c(1,1)) } sub.plot <- function(ss,gamma, prv) { plot(c(5,20,50),ss[ss[,"gam"]==gamma & ss[,"prev"]==prv,"x_Power"], type = "n", xlab="4Nc", ylab="Power...

hi all another simple question. i've written a dummy program so that you get the concept. (the code could be simplfied such that there are no loops. but lets leave the loops in for now.) z1<-function(w) { for (i in 1:w) { set.seed(i+6) ss<-0 for (j in 1:5) { set.seed(j+1+(i-1)*6) r<-rnorm(1) ss<-ss+r } list(ss=ss) } } check.1<-z1(3) check.1 the results is: $ss [1] -0.01516304 what i want is something that looks like this: j=1 $ss [1] -2.213343 j=2 $ss [1] -2.904235 j=3 $ss [1] -0.01516304 i know that i c...

Not sure if there is an R way to do this or a regular express way, but here is what I am trying to do. I've got lots of data where the format is HH:MM:SS, but I need to format it like HH:MM:00, i.e. round the second down to zero. What is the best way to do this? Thanks again. Jason

Hi, We're encountering severe load problems associated with multiple smbd processes running per user. As an example below, this user has only five files open yet many smbd's running. Is there a reason for this occurring? I've been experimenting with file locking etc to try and get around it. Thanks Tim tim@hostname:~> smbstat...

I'm upgrading my primary server from RH 7.2 to CentOS-4.3.ServerCD. I REALLY like the ServerCD. Who needs all the fluff that comes with a standard distro? If I want a system-config-gooey I can run Xnest [1] and ssh -X from my laptop. Anyway I have two questions: 1) How can I collectively stop all the NFS, portmap, whatever? I'm hoping it can be manipulated as a group because occationally I actually will want to use NFS. 2) Can I safely turn off dbus, hal, and/or xfs? Or will something really bad happen...

...data output from a simulation model and creates some graphs. It's not very complicated code, and it works perfectly fine if I just run the code as is. But I have converted it into a function so we call it externally, and when I try to source the code to test the function, I get the error message "variable names are limited to 256 bytes". I've tried searching online for a solution to this, but everything I have come across deals with this error in relation to input data, not a function. The code is 389 lines long, so I'd rather not paste it here and clog up inboxes....
