similar to: RPgSQL, Rdbi.PGSQL, and Rdbi for Windows?

One quirk to be watched is the use of connections to the DBMS via the Unix sockets vs ports. The PostgreSQL driver bundled with unixODBC will use Unix sockets to `localhost', but this driver seems unreliable (see the ChangeLog). The current driver will only use a TCP/IP port, and to use that needs postmaster started with the -i flag (which is not the default) and with tcp/ip

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

Dear R-announce list members, I've submitted a new package to CRAN, Rcmdr, which provides a cross-platform basic-statistics GUI for R. Rcmdr is based on the tcltk package and uses only standard Tk widgets. It therefore runs under Windows if Tcl/Tk support is installed with R, although it requires the single-document interface (SDI). I've tested Rcmdr with Windows and Red Hat Linux;

Dear R and S list members: I've just published a book entitled An R and S-PLUS Companion to Applied Regression. The book introduces R and S-PLUS in the context of linear and generalized-linear models, and assumes familiarity with -- or a simultaneous course or text on -- these topics. I thought that the book might be of interest to the members of these lists or to their students. More

I've uploaded to CRAN a new package called effects. The package contains functions for tabular or graphical display of terms in a linear or generalized linear model, and is particularly suitable for models that contain terms -- such as main effects and interactions, or polynomial regressors -- related by marginality (hierarchy). A draft paper describing the package is located at

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?

Dear R-help list members, I'm encountering problems using expand.model.frame. To illustrate, consider the function > test <- function(model){ + expand.model.frame(model, "income") + } > The data frame Prestige (from the car library) has several variables, including prestige, income and education. I've attached this data frame >

Dear list members, I'm experiencing a variety of intermittent problems with GUI-related commands (e.g., for dialog boxes and graphics-device windows) in R for Windows running under XEmacs/ESS. I'm using version 1.6.1 of R, version 21.4.9 of XEmacs, version 1.02 of ESS, and various versions of Windows, including 2000, 95, and 98SE. The problems don't occur in every circumstance,

Dear list members, I was reminded of what I see as a problem with summary.glm this week when some of my students fell into a trap in a homework exercise, defining a logit model in which coefficients were aliased. When this happens in lm, summary.lm prints a message ["Coefficients: (1 not defined because of singularities)"], but summary.glm is silent. In both instances, the print

Dear r-devel list members, I've prepared a version of the Rcmdr package that uses the new tools for internationalization and localization in R 2.1.x. For the present, this is the development version of the Rcmdr package (1.1-0), available at <http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/index.html>. There is currently a French translation provided with the package, courtesy of

Dear R-help list members, Yesterday, I described a problem that I encountered with the use of expand.model.frame when the model object passed to this function was created without an explicit data argument in the call. I've had no responses, but I've been able to work around the problem by making a change to expand.model.frame, replacing the line rval <-

Dear R-announce list members, I've uploaded to CRAN a new version of my Rcmdr package, which provides a cross-platform basic-statistics GUI for R. This version has a few new features, but mostly addresses some problems that arose with the original version. The relevant portion of the CHANGES file for the package is appended. As before, suggestions and reports of problems are appreciated.

Dear list members, I've just uploaded version 1.0-0 of the Rcmdr package to CRAN. For people who haven't seen the package before, the "R Commander" provides a basic-statistics graphical user interface to R, based on the tcltk package. The new version incorporates a number of improvements to the R Commander interface, as documented in the CHANGES file distributed with the

When this happens in lm, summary.lm prints a message ["Coefficients: (1 not defined because of singularities)"], but summary.glm is silent. In

Dear list members, I and my students have encountered an intermittent problem using the Rcmdr package (version 0.9-0) under Windows (with the SDI). The problem occurs both in versions 1.7.1 and 1.8.0 of R. The problem seems to occur only in the following context: The "Edit data set" button is pressed in the Rcmdr GUI. This executes the fix() function on the active data frame,

Dear R list members, I'd like to produce rug plots at the bottom of panels in a trellis display (using the lattice package), but par("usr") doesn't return user coordinates for panels, and consequently rug fails, as the following example (suggested to me by Georges Monette) illustrates: > x <- rnorm(50) > y <- rnorm(50) > f <-

Dear R-help list members, I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent work on the tcltk package, almost everything has gone very smoothly. I'm stymied, however, by the following problem: I want to incorporate a bitmap image, stored as an xbm file, in a widget. To take a simple example, top <- tktoplevel() tkgrid(tklabel(top,
