Hi all, I''ve got overlapped and offset support in both nread and nwrite. The only thing left before I want to release this (as 0.4.0) is to get NO_BUFFERING to work. Unfortunately, I can''t get it to work. Park, I looked at that site you sent (and borrowed some code from it), but I don''t see anything special happening for NO_BUFFERING. I thought it required

I have been doing data analysis/modeling in R, connecting to SQL databases with RODBC (winXP client with R1.9.0 and win2k SQL server 2000). I am now trying to leverage some of the OLAP features to keep the data intensive tasks on the DB server side and only keep the analytical tasks within R (optimize use of memory). Is there any package that would allow to connect to OLAP cubes (as a client

Hi All, I have an CBS segmentation algorithm output for 10 tumor samples each from 2 different tumors. Now, I am in an urgent need to assign gene (followed by all genes present) that belong to a particular segment after I removed all the CNVs from segment data. The format of the data is: Sample Chromosome Start End Num_Probes Segment_Mean Sample1A-TA 1 51598 76187 15

Hi @ all Does anyone has some experience with PostgreSQL and RoR? Does it gives any disadvantages or problems with PostgreSQL? I have a webapplication, that manage (read/write) many records (no. 200''000 records) and I search a ideal database. Actually, I have two options: - MySQL / - PostgreSQL And now, I would like to ascertain a good solution... Thx, ribit -- Posted via

Hi, Lang As a starter using LLVM JIT to improve OLAP execution engine performance, I'm very glad to hear that. I can't find some useful document help me get start to use the new ORC JIT API quickly. Only can find some examples how to use it, but don't know the internal from low level, and very blurred to design a clearly JIT toolset. Hope more tutorials add in and help ORC JIT more

Is there any way that a model can be based on a stored procedure or function that so that it can return a set of data based on a parameter provided in either the controller, or s a variable in the model? That way you could: 1) Set the variable 2) Call find_all 3) Get a mutable set of results that takes better advantage of some of the advanced database features available?

Hi guys/girls, How are you ? I'm running "Linux 2.4.22 SMP" with Samba-3.0.4 and pick up the following message in my syslog when accessing a mounted NT4 share: kernel: smb_proc_readdir_long: name=\OLAP Services\Data\GreatPlains\*, result=-13, rcls=1, err=5 Any ideas what this is ? Your assistance is greatly appreciated. Many thanks. Kindest regards David Wilson D c D a t a Tel

Dear all, in last weeks you discussed about R vs SAS. I want to ask your opinion about a comparison between R and SPSS. I don't know this software, but some weeks ago I went to a presentation of this product. I found it really user-friendly with GUI (even if I'd prefer command line) and very usefull and simple to use in creation and managing tables, OLAP tecniques, pivot table. What you

1. That was a part of a private email exchange. It has been suggested that more people may be interested. 2. I did use various databases (significant part of my job) for the last 15 years. Some with R for the last 3 years as a hobby. Some comments on the ones used below. Sorry, no links - I am time-constrained at the moment - please google if interested in details. The remarks are from the point

Hi, I''m new to RoR and exploring its use with an existing application. One thing I can''t seem to find much detail on is using database triggers. All RoR examples and tutorials I''ve seen are very basic saving data back to a single table. My use case includes a somewhat denormalized DB that uses triggers to store data in multiple tables on occassion. I currently

tabulate has .C("R_tabulate", as.integer(bin), as.integer(length(bin)), as.integer(nbins), ans = integer(nbins), PACKAGE="base")$ans The implementation of R_tabulate has if(x[i] != R_NaInt && x[i] > 0 && x[i] <= *nbin) and so copes with (silently drops) NA. Perhaps the .C could have NAOK=TRUE? This is useful in apply'ing tabulate to

Dear all, it looks like that tabulate() does not check for the bounds of the input. Reproducible example: > b <- 1:2 > tabulate(b[1:100]) [1] 1 1 > R.version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status Patched major 2 minor 11.1 year 2010 month 09 day

Dear list, I have data like this: dat1 <- data.frame(subject=rep(1:10,2), cond1=rep(c("A","B"),each=5), cond2=rep(c("C","D"),each=10), choice=sample(0:1,10,replace=TRUE)) I would like to compare subjects' "choice" for (cond1=="A" & cond2=="C") vs

Hi, I have written a code in R for classifying microarray data using naive bayes, the code is given below: library(e1071) train<-read.table("Z:/Documents/train.txt",header=T); test<-read.table("Z:/Documents/test.txt",header=T); cl <- c(c(rep("ALL",10), rep("AML",10))); cl <- factor(cl) model <- naiveBayes(train,cl);

Hi, i have some problems to get means, but the data have got NA's which should not be replaced or delete ! tapply(data,var,mean) # makes me problem,because when one value is NA mean is NA,too. Another attempt is this, because the summary does what i want , but is not subsetable to summary[4] if i use tapply,table and the the function below gives me again all means as NA ? xmean
