Hi, Is there an R library that has the same functionalities of Splus7.0+ library correlatedData? I'd appreciate any input. Hakan Demirtas [[alternative HTML version deleted]]

Hi, Is there any R library/package that calculates tetrachoric correlations from given marginals and Pearson correlations among ordinal variables? Inputs to polychor function in polycor package are either contingency tables or ordinal data themselves. I am looking for something that takes marginal distributions and Pearson correlation as inputs. For example, Y1=(1,2,3) with P(Y1=1)=0.3,

Hi, If a matrix is not positive definite, make.positive.definite() function in corpcor library finds the nearest positive definite matrix by the method proposed by Higham (1988). However, when I deal with correlation matrices whose diagonals have to be 1 by definition, how do I do it? The above-mentioned function seem to mess up the diagonal entries. [I haven't seen this complication, but

Hi, Is there any Fortran compiler that generates R-compatible object files ? (For Windows based systems) Thanks, Hakan Demirtas Pennsylvania State University Department of Statistics [[alternate HTML version deleted]]

Hi, Is there any R library that is capable of handling polygamma function (Hurwitz zeta function also works)? I am aware of digamma(0 and trigamma(), but could not find more advanced versions. I'd appreciate any help. Hakan Demirtas

Hi, What R libraries should I use to implement mixed effects models with continuous time and discrete-time survival data? What if I have two crossed random effects? I'd appreciate any help. Regards, Hakan Demirtas [[alternative HTML version deleted]]

Hi, Suppose x and y are vectors whose elements are known. I know that there is a sinusoidal relation between them. In other words, y=a*sin(bx) where b is probably a function of pi. How do I find a and b in R? Hakan [[alternative HTML version deleted]]

Does lmer do three-level mixed-effects models? What forms of outcome variables can it handle (continuous, survival, binary)? I'd appreciate any help.

I am trying to incorporate random effects (random intercept is good enough) to a proportional odds logistic regression model for ordinal outcomes. Could lme4 do this? I'd appreciate any input. Hakan Demirtas

This may be a nginx issue more than a mongrel one but I though folks in this list might be interested. Anyway, I have a mongrel_cluster with 2 front nginx workers as proxy. I recently replaced apache/mod_proxy for nginx, and I wasn''t aware of the 60 seconds default proxy_read_timeout so I went a head and tried to run a process via http GET. Normally because of the 60 seconds the GET I

Recently I ran into a situation where an ocfs2 (1.4) volume was reporting it was out of space when it was not. Deleting some files helped short term but the problem quickly comes back. I believe this is due to the fragmentation bug that I have seen references to in the mailing list archive. I am trying to reproduce the problem on a test system so that I can validate that upgrading to 1.6

Hi, I was wondering if anyone would know the cons of running a PAE kernel...? I have a 4GB pc and was wondering if it was worth going the PAE way to gain those exta 700MB... In the past, I heard that these 700MB were normally reserved for bios or chipset stuff... And that running in PAE would slow down some processes. By the way, I know 64 bits would solve this dilemn but right now I am
