search for: s3method

Hi, I was trying to get a list of S3 method for a given generic, along with the package in which they are defined, and I came across what looks like an issue in the data.frame returned in attribute 'info'. The column 'from' mostly gets the value "registered S3method for ..." except for visible methods. Is this the expected behavior? See code and output below. Thank you. Bests, Renaud $ Rscript -e "library(xtable); attr(.S3methods('plot'), 'info'); sessionInfo()" visible from generic...

R-exts.pdf discribes S3method a little bit. But I want to understand more on how it is called, implemented and when to use it. I don't find it in an R session.

Hi, from the man page ?methods, I expected to be able to build pairs (class,package) for a given S3 method, e.g., print, using attr(methods(print), 'info'). However all the methods, except the ones defined in base or S4 methods, get the 'from' value "registered S3method for print", instead of the actual package name (see below for the first rows). Is this normal behaviour? If so, is there a way to get what I want: a character vector mapping class to package (ideally in loading order, but this I can re-order from search()). Thank you. Bests, Renaud...

Dear all, I have defined a generic as.ff(x, ...) and a method as.ff.function(x, ...) which converts a standard R function x into a chunked version operating on large ff objects. Everything works fine, but when registering S3method("as.ff",function) in NAMESPACE, the installation fails with some kind of parsing error: adding build stamp to DESCRIPTION installing NAMESPACE file and metadata Fehler in parse(nsFile) : Unerwartetes ')' bei 348: 349: S3method("as.ff",function) Calls: <Anonymous...

If I call .S4methods(sd) I get the error ## Error in getGeneric(generic.function) : ## argument 'f' must be a string, generic function, or primitive: got an ordinary function By contrast, methods and .S3methods just state that no methods are found. methods(sd) ## no methods found S3methods(sd) ## no methods found It seems like the behavior of these functions ought to be consistent. Maybe they should split the difference and say no methods are found, but warn the the input is not generic? -- Regards,...

It contains a number of objects; it looks as though one of yours called "S3methods" is corrupted. I can't guess whether it is one coming from staRdom or one already in your library, but it appears yours doesn't have the usual number of columns (which I think is 3). So you could get a list of all packages in your library, and run sapply(allpackages, function(x)...

I have updated the rms package to extensively use NAMESPACE. I cannot get certain S3 methods to dispatch. For example I have in NAMESPACE S3method(anova, rms) S3method(latex, anova.rms) anova.rms produces an object of class "anova.rms" and there is a latex.anova.rms function in rms. But when I do latex(anova(fit)) I get an invocation of latex.default. I have tried using "anova.rms" and `anova.rms` in S3method() to no av...
