The problem is not specific to redefining the q function, but to the interaction of assignInNamespace and setGeneric. The latter requires, roughtly, that the environment of the function being replaced by an S4 generic is (or is the descendent of) the environment in which it lives. E.g., the following demonstrates the problem % R --quiet --vanilla > assignInNamespace("plot", functio...

A coworker got tired of having to type 'yes' or 'no' after quitting R: he never wanted to save the R workspace when quitting. So he added assignInNamespace lines to his .Rprofile file to replace base::q with one that, by default, called the original with save="no".. utils::assignInNamespace(".qOrig", base::q, "base") utils::assignInNamespace("q", function(save = "no", ...) base:::.qOrig(save = sa...

Hello, assignInNamespace refuses to assign an object to a name that is not already used in the namespace.

...er("PostgreSQL"), user="blah","blah") } .onUnload <- function(libpath) { dbDisconnect(.bbg.db.conn) } which results in a hidden global variable in the global environment. I would prefer to make the assignment only in the package namespace. I've looked at assignInNamespace, but I can't seem to make it work. Is there a preferred method for doing this? When I try adding an assignment directly in the source file, I get the "cannot change value of locked binding" error. What am I missing? Thanks, Whit

Brian Ripley recently replied to a comment of mine by referring to a function 'assignInNamespace', which I had not heard of. Is there a good write up on name spaces in R? There are little tidbits in the manuals on the R site, but I found nothing substative. I'd like to understand these better. Terry Therneau

...if further debugging is needed ... other alternatives are being explored ... ". Is renaming/removing the NAMESPACE file still the favored approach when developing and debugging code for an R package? I suppose the alternative I have in mind is something like sourcing an R file, and using assignInNamespace(), may be more trouble than it is worth. I am doing this development using ESS by the way. Thanks for any guidance! Erik Iverson

...mes necessary, internal hackery, hence the title.) The problem is I can't figure out how to override +.POSIXt so that it gets called from +. Simply including a new +.POSIXt function in the package doesn't work because (I presume) + finds and uses base::+.POSIXt. The next thing I tried was assignInNamespace("+.POSIXt", lubridate::`+.POSIXt`, "base") but that doesn't seem to work either, despite the documentation: "They do attempt to alter a copy registered as an S3 method if one is found." (perhaps there is a missing not there?) In desperation, I also tried the fo...
