Dear list members, I've uploaded a new package, called polycor (version 0.5-0), to CRAN. The package has functions for computing polychoric and polyserial correlations, either by maximum-likelihood (in which case, standard errors are available) or by...

Dear list members, 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 instructions about how...

Dear Philippe, Take a look at effect, all.effects, and related functions (such as plot methods) in the car package. It will probably do what you want, and works for linear and generalized linear models. A slightly more general version...
