Hello everyone! Congratulations by this gorgeous software. My name is Germán Carrillo, I'm writting from Colombia. I don't have much experience with R, reason why I use the R-GUI (version 2.5.1) on Windows. I have some problems with DBI package, I want to connect to PostgreSQL database but I don't know the way to do it. I was reading the DBI manual and I tried write in my R Console

Hi, I'm running Debian (Sid), Postgres (7.3.4) and R (1.8.1). I get the following error when I tri to use DBI >library("DBI") > p <- dbDriver("PostgreSQL") Error in do.call(as.character(drvName), list(...)) : couldn't find function "PostgreSQL" Is there any other package I need in order to interface between R and Postgres ?

Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

Dear all, I have a matrix X with 47 lines and say 500 columns - values are in {0,1}. I'd like to compare lines. For that, I first did: for (i in 1:(dim(X)[1]-1)) for (j in (i+1):dim(X)[1]) { Y <- X[i,]+Y[j,] etc. but, since it takes a long time, I would prefer avoding loops; for that, my first idea was to add this matrix: X1=X[,rep(1:46,46:1)] to this one: res=NULL for (i in

Hi R-users I recently downloaded RdbiPgSQL 1.8.0 and Rdbi 1.8.0 from Bioconductor to be installed under R 2.4.1. When requiring RdbiPgSQL an error message is showed as follows: > require(RdbiPgSQL) Loading required package: RdbiPgSQL Error in library(package, lib.loc = lib.loc, character.only = TRUE, logical = TRUE, : ‘RdbiPgSQL’ is not a valid package – installed <

Dear All, I have a data, suppose it is an N*M matrix data. All I want is to classify it into, let see, 3 classes. Which method(s) do you think is(are) appropriate for this purpose? Any reference will be welcome! Thanks! Best, Baoqiang Cao

I cannot operate lattice plots, notably those in package gstat, within for() loops. (I can neither read such graphics included in a .R (or .txt) file with the source() function). However same commands executed one by one don't fail. Could you please help me find a means to execute lattice plots inside a loop ?

Dear R-users, Someone, who uses R under Mac, wants to insert a couple of small plots (each with several lines) in an article, but he has to reduce plots' size significantly. He did it (in pdf or enc. ps) but, unfortunately, everything is reduced but lines' width. Besides, 'lwd' argument in par() or plot() can't be less than one. I am not a Mac user and I don't know

Dear all, I tried to use layout argument in xyplot to get one panel per page. I have a dataframe named 'data' with the following variables: x, y = coords, sub, bloc = 2-level factors, etat = 5-level factor, I did : > lset(theme = col.whitebg()) > xyplot(y ~ x | bloc*sub , data=data, groups=etat, + layout=c(0,1,4), + main="Etat des plantes dans chaque

Dear R-users, Is there an easy way to avoid points one upon another when ploting rows and columns of 'dudi' objects ? Maybe there is a function in ade4 or in an other package, or maybe someone has his or her own function to do this (for example to automatically modify a little the coordinates of these points to get a readable plot ?). Thanks in advance. Best regards, Jacques VESLOT

To get the Rdbi/RdbiPgSQL 1.0.1 interface from BioConductor functional, I would like to suggest some fixes. Find patches and the updated packages here: http://mpa.itc.it/markus/tmp/rdbi/ Changes Rdbi: - fixed load of RdbiPgSQL (wrong name) - fixed dbConnectionInfo() (typo) RdbiPgSQL: - fixed table export to PostgreSQL - added make.names() to polish column names for R usage

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

I have been using RODBC for a while with no complaints (R 2.0.1 patched under WinXP), then I saw a link (http://grass.itc.it/statsgrass/r_and_dbms.html) showing that Rdbi claims to run a query in 5 seconds that takes RODBC 4.3 minutes. That was hard enough for me to believe that I wanted to try some tests myself, but I cannot get Rdbi to connect to my ODBC database. Here is what works for RODBC

one more bit of information about this problem. If I start R as the user "postgres" i dont have the segmentation fault. ---------- Forwarded message ---------- Date: Wed, 5 Feb 2003 19:19:39 -0500 (EST) From: Rafael A. Irizarry <ririzarr at jhsph.edu> Reply-To: rafa at jhu.edu To: "R-Help (E-mail)" <r-help at r-project.org> Subject: rdbi segmentation fault hi! i

I can use the Rdbi package to connect to a PostGreSQL server fine but when I use the dbDisconnect(), I get a segmentation error and it throws me out of R. I'm using RH7.2, R1.4.1, Rdbi 0.1-2, and Rdbi.PgSQL 0.1-2. Anyone else seen anything like this and have an possible answer?

I have a simple vector, called tmp that I want to subset based on another vector called vec. Everything works as expected except for below where the subsetting returns something other than the original data. Any ideas? > vec <- c(1,2,3,4,5,59,60,27,32,21) > tmp [1] 1.0 1.1 2.0 2.1 2.2 3.0 3.1 4.0 5.0 5.1 6.0 7.0 8.0 8.1 9.0 [16] 9.1 9.2 10.0 10.1 11.0 12.0 13.0 14.0

hello, I wish to create some 3d scatter diagrams visualising different grouped data set by a given field in the database. I tried the scatterplot3d package, as well as the plot3d and scatter3d functions (both within the rgl resp. Rcmdr package). My first question is, whether is it possibe to group data in the scatterplot3d and plot3d, because I did not succeed to use the groups = ...

I usually work with R on a windows querying data through RODBC from a postgresql db on a freebsd machine on my offcie lan. Now I have the chance to use R also on a linux gentoo client box and to connect to the same db. I know that I can install the unixodbc stuff and stick to RODBC, BUT my question is: Is there any more 'linuxish' way of querying a postgresql server from a client?
