similar to: S3 method for package listed in suggest/enhance

Hello, I try to set up namespaces for packages. It is fine for several of them, except one whose compilation fails (under Windows XP & R 2.0.0): ---------- Making package svViews ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata Error in parse(file, n, text, prompt) : syntax error on line 21 Execution halted make[2]: *** [nmspace] Error 1 make[1]: ***

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:

PkgA wishes to write a method for 'unique' on S4 class 'A'. ?Methods indicates that one should setGeneric("unique") setClass("A") unique.A <- function(x, incomparables=FALSE, ...) {} setMethod(unique, "A", unique.A) Both S3 and S4 methods need to be exported in the NAMESPACE import(methods) S3method(unique, A)

Dear List, In one of my packages I have an S3 method for the plot3d generic function from package rgl. I am trying to streamline my Depends entries but don't know how to have plot3d(foo) in the examples section for the plot3d method in my package, without rgl being in Depends. Note that I importFrom(rgl, plotd3d) and register my S3 method via S3Method() in the NAMESPACE. If rgl is not in

Dear listers, After activating the name space for my bioconductor package (prada) I successfully ran R CMD check. However when loading the package in R and running the examples the imported function brewer.pal from package RColorBrewer is not found. I can directly call brewer.pal from the RColorBrewer name space typing RColorBrewer::brewer.pal, but it is not imported into my prada name space. When

In my own package, I want to use the default S3 method of the generic function lrtest() from the lmtest package. Since I need only one function from lmtest, I tried to use importFrom in my NAMESPACE: importFrom(lmtest, lrtest) However, this fails R CMD check in the examples: Error in UseMethod("lrtest") : no applicable method for 'lrtest' applied to an object of class

Dear all, I am encountering a cyclic dependency error when running R CMD check on an R package I wrote (R version 2.6.1, Mac OS X 10.4), see the error message below. Creating a new generic function for "print" in "clValid" Creating a new generic function for "summary" in "clValid" Creating a new generic function for "plot" in

Hi, I am currently involved in the development of two R-packages, pkg1 and pkg2. They should not be dependent on each other, as most users will only be interested in one of them. Still, I want pkg2 to provide one extra S3 method for three functions (fun1-3) in pkg1 for objects of a class defined in pkg2 (class2), for those users who actually have both packages installed. I think this

In this post https://stat.ethz.ch/pipermail/bioc-devel/2013-March/004152.html a package author reports that S4 dispatch fails. I can reproduce this with a PkgA (attached; 'intervals' is a relatively light-weight CRAN package) that has DESCRIPTION with Depends: intervals Imports: graphics NAMESPACE: importFrom(graphics, "plot") export("plot")

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 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

Hi, I have already asked a similar question without response (https://stat.ethz.ch/pipermail/r-help/2009-June/200300.html) so I am here reformulating in the hope that someone is able to help. If something is unclear, please ask. I am working on the development of two packages, pkg1 and pkg2 (based on work in two different projects). pkg1 is quite generic, pkg2 tries to solve a particular

Dear all, I am developing a package, which bundles my most frequently used functions. One of those is a modified version of droplevels from the base package (basically, it preserves any contrast function which was used to create the factor, contrast matrices are not kept, for they could be wrong if a level is dropped). In my NAMESPACE file I've the following directives, which should export

Dear list I'm not sure whether this is a bug or an unavoidable consequence of the way packages are loaded, but there can be surprising side effects of calling a function via package::function. Here's an example using the formula.tools package: form <- a ~ b as.character(form) formula.tools::lhs(form) as.character(form) The first call to as.character returns: [1] "~"

Hi, I have already asked a similar question twice without response on the r-help list https://stat.ethz.ch/pipermail/r-help/2009-June/200300.html but this list might be more appropriate. If there is a particular reason for the lacking answers (unclear, missing information, the solution is obvious to everyone except me, etc), I would like to know. The description below is generalized, but I

Now I try to add some C and Fortan code to my package, so the NAMESPACE file is useDynLib(eha) importFrom(survival, Surv) export(mlreg.fit, risksets) but I get ..... * checking R files for library.dynam ... OK * checking S3 generic/method consistency ... WARNING Error in .try_quietly({ : Error in library(package, lib.loc = lib.loc, character.only = TRUE, verbose = FALSE) :

Can anyone help me figure out the right way to import a method that is defined as S3 in one package and S4 in another? Specifically: profile() is defined as an S3 method in the stats package: function (fitted, ...) UseMethod("profile") <bytecode: 0xa4cd6e8> <environment: namespace:stats> In stats4 it is defined as an S4 method: stats4:::profile standardGeneric for

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 ...
