Hello list, I've been trying to get the PostgreSQL PL/R library to compile on windows (http://www.joeconway.com/plr/). The author of this library says the problem is likely because the distributed R.dll isn't compiled as a shared dll. Is this the case? If so, is there any way to compile it such that it is shared? If that's not the case, than maybe someone on this list has a better

Dear R-users I have problems using lme The model i want to fit can be viewed as a two-level bivariate model Two-level bivariate: bivariate (S coded as -1,T coded as 1) endpoint within trial OR It can equivalently be considered as a three-level model.Three-level: endpoint within patient, patient within trial. My code tries to model the levels through a RANDOM statement and a

hi all i have a function that uses two inputs, say xdata and ydata. An example is the following, simple1<-function(xdata,ydata) { ofit<-lm(ydata~xdata) list(ofit) } say i use arbitray number for xdata and ydata such that D = x1 x2 y 1 1 10 2 6 6 3 10 7 x<-D[,1:2] and y<-D[,3] if one uses these inputs and rund the program we get the following: >simple(xdata=x,ydata=y)

Hello, I've been struggling with a problem for the past several weeks, trying to get PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) to work on Red Hat 9. In brief, R dumps core during the embedded library initialization, while in Rf_regcomp(), working on on Rprofile. Below I've included the important parts of a backtrace: Program received signal

Hi R-helpers Has anyone had any experience doing CGI or Servlets or using an httpd server in R? Context: we are interested in running dynamic demographic calculations on the internet (life tables, and such) in response to form submissions. I might do simple cgi to get started, but loading in data each time seems like it would be quite, quite slow. I have looked at Rserv, but I am most

Dear all, I just found that some of the packages are not able to load any more, after I installed R2.0.1 in my Mac, it even affects my old R1.8 installs. It gives me errors when I load packages that contains "myEnv" settings. such as: RMySQL, DBI, Rggobi, etc. But others that does not require "myENV" is all right, like tcltk that only calls the c functions. The errors

Hello, I've been using R embedded in PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) very successfully for several months now. A sincere "thank you" goes to the R development team for such a great product. I have a question I'm hoping someone here can help me with. In order to get the required functionality out of PL/R, I've had to

Friends I am starting on a (section of the) project where I need to build a matrix with on the order of 5 million rows and 200 columns I am wondering if I can stay in R. I need to do rollapply type operations on the columns, including some that will be functions of (windows of) two columns. I have been looking at the ff and bigmemory packages but am not sure that they will do. Before I get

Hi all, I am currently trying to create a development environment including PostgreSQL 8.0.0rc1, R 2.0.1 and PL/R on a system running Fedora Cora 1. So far, I have suceeded in setting up PostgreSQL and R as a shared library - unfortunately I have not been able to link these two spheres by adding the PostgreSQL add-on PL/R due to some mysterious probs. I thoroughly followed the setup

Hi all, I am working on a bug, which running PLR on HAWQ. The process hung and can't be terminated. >From my investigation, it seems signal handler 'Rf_onsigusr1' trigger a malloc/free deadlock.

Hello All, I am new to R. I am trying to process this huge data set of matrix containing four columns, say x1, x2, x3, x4 and n number of rows. I want to aggregate the matrix by x1 and perform statistic based on columns x2, x3, x4. I tried aggregate function but it gave me memory allocation error (which I am not surprised), so I ended up performing a for loop based on x1 and

Sorry for the simple question: What is the "standard" package for interfacing with PostGreSQL (most up-to-date)? There appear to be at least three with different names: Rdbi.PgSQL RdbiPgSQL (available as part of BioConductor) RPgSQL (On the home page, no longer maintained in favor or Rdbi) The R and database developer page (http://developer.r-project.org/db/) was last updated in

Dear R-users, I am faced with the problem of analyzing a huge dataset (+ 2 million records, +150 variables) which does not fit into memory. I would like to know if there are pre-packaged tools (in the spirit of Insigthful I-Miner, for instance) aimed at subsampling or splitting the dataset into data-frameable subdatasets, applying functions record-wise, etc. Thank you very much for your

Don't know if this is the correct place to post this question however I thought I would start here. The Fedora 1 packages are built without the option '--enable-R-shlib' turned on in the R.spec file. Other software, like, plr (the postgresql library that calls R) needs the shared lib. Any chance that we can change the R.spec file to include: [iwallace at localhost SPECS]$ diff -bu

Hi - I am new to RandomForest and want to be able to predict for a set of values outside of R. So for example, if I create the model in R and want to get the prediction for an observation in a database, is there a way I can get the algorithm for the trees and final prediction for this model printed out in R that I can directly implement in SQL? Or is the only way to do this is to use a wrapper

Dear R-list, Realising the importance of updating the R base, I tried to compile the source file of R2.2.1 in my machine, but failed. According to "R for Mac OS X FAQ", i've got the basic dependencies which are gcc 3.3 and g77 3.4. ./configure is fine Here are the errors I got from make: >make ... gcc -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre

In case anyone is interested, here is a link to an online article written by someone in the Postgres community, covering PL/R: see (cover): http://www.varlena.com/varlena/GeneralBits/66.php and follow to (article): http://www.varlena.com/varlena/GeneralBits/Tidbits/bernier/art_66/graphingWithR.html PL/R is a procedural language handler for PostgreSQL, that allows Postgres functions to be

Hi I am using R as a back-end to some CGI scripts, written in Perl. My platform is Suse Linux 8.2, Apache 1.3.7. So the CGI script takes some form parameters, opens a pipe to an R process, loads up some Bioconductor libraries, executes some R commands and takes the ouput and creates a web page. It is all very neat and works well. I am trying to make my cgi scripts quicker and it turns out

Dear all, i am trying to get PL / R running on Mac OS X. PostgreSQL is already running and connects just smoothly to R via DBI / RPostgreSQL . Despite finding a couple of posts of people with the same problem (i.e. error message) i could not get it done for me. I use Mac OS 10.5.7 and PostgreSQL 8.3.7 as well as R 2.9.2 I put the untared plr to my /Library/Frameworks/R.framework/Resources/
