Hierarchical Bayesian Modeling in R
Hi Friends, I'm trying to model the consumer decisions (Click-Through Rate and Conversion) in Search Engine Advertising using a hierarchical Bayesian binary logit. The input data is the weekly CTRs and Avg. Position for each search keyword. CTR is modeled as (for each keyword i and week j): Pij = exp(C + Bi x Positionij + A1 x Lengthi + A2 x Brandi + A3 x ProductSpecifici) / [1 + exp(C +

C function is wrong under Windows 7
Dear mailing list, I have a C function that gives me a wrong result when I run it under Windows 7.

Errors in in my code
Hi Everyone, I am very new to R. When i run the code yesterday, it was working fine. I was able to find gene annotation. somehow, today, when i try to run it again, it is giving me errors message that i don't understand. It says that it cannot open file. what file is it looking for? ###################################################### ##make sure to install and load annotationtool in R

Memory problem ... Again
Happy new year to all; A few days ago, I posted similar problem. At that time, I found out that our R program had been 32-bit compiled, not 64-bit compiled. So the R program has been re-installed in 64-bit and run the same job, reading in 150 Affymetrix U133A v2 CEL files and perform dChip processing. However, the memory problem happened again. Since the amount of physical memory is 64GB, I think

A question about memory size
Hi.... I have a question about how to increase my memory size, could someone answer it for me?? I am using Bioconductor in R to calculate gene expression values with mas5, dchip, and mas4. I have only 18 samples, all from Affymetrix U133A Plus 2 arrays, which has ~54,000 genes. My machine equipments are: CPU P4 3.0GHz, and 1GM RAM. Somehow when I was running mas5 in R, it always showed the error

memory problem
I am trying to upload into R 143 Affymetrix chips onto using R on the NIH Nimbus server. I can load 10 chips without a problem, however, when I try to load 143 I receive a error message: cannot create a vector of 523263 KB. I have expanded the memory of R as follows: R --min-vsize=10M --max-vsize=2500M --min-nsize=10M -max-nsize=50M (as specified in help in R). After running this command the

Help with SOM membership
Hi all, I originally posted this to the bioconductor group, but maybe it's better suited to the r-help... I'm using som() to partition samples of gene expression data into clusters. The point is to classify control vs. experimental cases (sample clustering). The original matrix was 22283 x 8. The 8 samples have 4 controls and 4 experimentals. I transposed the matrix so that its dim
