_______________________________________________________________________________________ Hi, When I create multiple graphs subsequent graphs overwrite previous graphs. How do I keep all my graphs in the current workspace (but not all on the same page) so I can scroll through them? thanks, Rohini Rohini Mulford Senior Research Analyst Technical Research Research &

_______________________________________________________________________________________ Hi, I'm writing up the online help for a package I'm developing (in-house only, sorry), and I've come across an odd glitch when trying to nest a list inside the "arguments" section of the .Rd file. I was just wondering if anyone could provide some insights. I'm using R 2.2.0 on

_______________________________________________________________________________________ Hi, I was just wondering if there was any available R code that could handle general constrained optimisation problems. At the moment I'm using nlminb and optim, both of which allow box constraints on the parameters, but ideally I'd like to be able to specify more general constraints on the solution

...level random intercept model, with 90,000 cases and about 330 groups. I'm unable to get any results on the full data set. I can get it to work if I sample down to about 30,000 cases. But for models with N's much larger than that I get the following warning message: m3=glmmPQL(prepfood~iage+iemployed+iwhite+ieduclevl+imarried+servcomm+leadgrup+leadsty4, family=binomial, random=~1|congrega1,data=data) Error: cannot allocate vector of size 4135 Kb In addition: Warning message: Reached total allocation of 253Mb: see help(memory.size) I've tried increasing my virtual memory size, a...

Hi all, I had the need to create a colorbar considering the alpha channel of the colors, but colorRamp() and colorRampPalette() ignored the alpha argument in rgb(). So I performed some minor modifs. in their codes, as to support the interpolation using the alpha channel. I guess that those simple modifications might be useful for other people, so perhaps it would be worth to add them to

Thomas, As F Harrel in a preceding message told me that you are the maintainer of Hmisc package, I write directly to you, with copy to the Rhelp list in case someone encountered the same problem and find some benefit in the response. I used quite often the function sas.get in Hmisc library which I is very, very useful. But, as trying to reuse it today it seems not to function anymore. I tried

Dear all, I tried to use "step" function to do model selection, but I got an error massage. What I don't understand is that data as data.frame worked well for my other programs, how come I cannot make it run this time. Could you please tell me how I can fix it? ***************************************************************************************************

I just picked up a Sony DRU-820A, 2 layar, DVD+-R, +-RW, RAM drive. It seems to be ok in the normal modes, but I'm not sure what I need to due with the RAM usage. I have some DVD-RAM disks. I put one in on the off chance it would just work, but it said it wasn't formatted. What do I need to due to use the this in RAM mode. I didn't find anything that seemed to be aimed at this.

Hi list, could anyone please educate me on the following: lst<-seq(47, 239, by=12) for(n in lst) { lower=n; upper=lower+10 for(i in lower+2 : upper) { print(paste(n, " i: ", i, " lower: ",lower, " upper :", upper)) } } does not stop when i = upper A while loop fixes this but, I still don't understand why the for loop doesn't stop

_______________________________________________________________________________________ Hello, Not sure if this counts as a bug or not, but I just noticed in R 2.4.0 that : and interaction are not quite equivalent. For example: > x <- factor(letters[1:4]) > y <- factor(letters[11:14]) > x:y [1] a:k b:l c:m d:n Levels: a:k a:l a:m a:n b:k b:l b:m b:n c:k c:l c:m c:n d:k d:l d:m

Dear R specialists, I have a multivariate statistics question that I want to submit to the R community (which conveys a very good statistical knowledge). I need to perform an optimal scaling based on a discrete variable and an ordinal variable. The discrete variable, Area, defines a geographical area. The ordinal variable, EducationLevel, describes the education level of individuals (the

Hello, I'm a grad student in the Intelligent Transportation Systems lab at Portland State Univ. in Portland, OR, USA. I'm trying to learn the basics of R to run a negative binomial in the near future, and so I ran a test regression on roadway crash data obtained from "Statistical and Econometric Methods for Transportation Data Analysis" by Washington et al (p. 250). I ran the

Red Hat 8.0 stock dovecot 99.10 for a variety of reasons, I decided to cut over to dovecot this morning. I extracted all of my mailboxes from mbx purgatory back to mbox purgatory, set up dovecot and proceed to get authentication failures. (am using simple password based authentication either direct or through pam) I turned authentication verbosity on and got: Aug 14 11:51:38 harvee dovecot:

I am just starting with R and have the following problem: given a matrix of ones and zeroes, say mdim=4 m<-matrix(round(runif(mdim^mdim)),mdim,mdim) how to construct the matrix of those rows of m, whose elements sum to 2. Contrary to the random matrix above, the actual matrix always has at least one such row. Serguei Kaniovski

Dear List: We are generating data such that students are clustered in schools for some item response data for a simulation study. One component of our simulation is to generate measurement error from a logistic distribution with a mean of 0 and standard deviation of 1.7 to match the logistic curve of the Rasch model. We are generating an error term for each of the 40 hypothetical test items a
