gReetings, I want to manipulate a formula object, containing the name "." so that "." is replaced by a desired (arbitrary) expression. What is a safe way to do this? Adrian Baddeley

Sorry, that should have been df <- data.frame(x=as.vector(rasterx.im(Z)), y=as.vector(rastery.im(Z)), count=as.vector(as.matrix(Z))) Adrian

Roger, thank you for those informative comments. I agree entirely. Thanks for the good suggestion about envelope() in spatstat. We will discuss this with the authors of the boot package. Adrian

Thanks, Brian. So, to print the version number when 'mypackage' is loaded, .First.lib <- function(lib, pkg) { library.dynam("mypackage", pkg, lib) vvv <- read.dcf(file=system.file("DESCRIPTION", package="mypackage"), fields="Version") cat(paste("mypackage", vvv, "\n")) }

I need to modify a glm object directly, by assigning new values to the fitted parameters. (i.e. the canonical parameters stored in object$coefficients and returned by 'coef'). Is there a "safe" way to do this, e.g. so...
