...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?

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. But I see S3method() in some NAMESPACE files. > S3method Error: object 'S3method' not found > ?S3method No documentation for 'S3method' in specified packages and libraries: you could try '??S3method' I

I am writing my first R package, and I have been getting the following series of errors when I run R CMD check: * checking S3 generic/method consistency ...

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

I am cleaning up the rms package to not export functions not to be called directly by users. rms uses generic functions defined in other packages. For example there is a latex method in the Hmisc package, and rms has a latex method for objects of class "anova.rms" so there are anova.rms and latex.anova.rms functions in rms. I use:

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

I define coef,

Hello, I try to set up namespaces for packages.

Hi In NEWS, it says R CMD check now tests that the package can be loaded, and that the package and namespace (if there is one) can each be loaded in startup code (before the standard packages are loaded). For package "onion", I think I have followed all of sections 1.6.1 - 1.6.6 of R-exts, and it passes R CMD check for R-2.3.1. However, using R version 2.4.0 Under

...#39; -- the namespace in which the generic to which the method belongs is defined, and the namespace in which the method is defined. I think the former is what you're interested in, but the latter likely what methods() might be modified return. For your use case, maybe something like .S3methodsInNamespace <- function(envir, pattern) { mtable <- get(".__S3MethodsTable__.", envir = asNamespace(envir)) methods <- ls(mtable, pattern = pattern) env <- vapply(methods, function(x) { environmentName(environment(get(x, mtable)))...

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
