similar to: missing imports not detected by 'R CMD check' (?)

Hello, I really need some insight on a problem we encountered using grid, lattice and gridExtra. I tried to reduce the problem, so the plot make no sense. we have a package: gridextrabug with: DESCRIPTION ------------------ Package: gridextrabug Title: gridextrabug Version: 0.1 Author: toto Maintainer: toto <karl.forner at quartzbio.com> Description: gridextrabug Imports: grid,

Hi, Since upgraded to R 2.15, I have a problem with duplicate S4 class name no longer works (the reason for having duplicate S4 class names is just software forks - they are largely identical but don't have an inheritence relationship, and will never have such). This is happening with "library(mypackage2)" : Error: package slot missing from signature for generic ?[? and classes

Dear all, It is my understanding that using 'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj'

Hi, I created a class (S4) with some slots like value, date, description (it's actually a financial transaction class). Now I need a method to convert this class forth and back into a single row data.frame, where every slots represents a column. This method looks at the moment like this: > setMethod("as.data.frame", "Transaction", function(x, row.names =

Dear R-devel list, Running the following example on a recent R-devel (here, 2016-11-22 r71672) shows that the byte compiler can cause some significant performance drops (here, computation time increasing from 0.01s to 0.31s ...) ================================= library(Matrix) someMatrix <- new("dtCMatrix", i= c(1L, 0:3), p=c(0L,0L,0:2, 5L), Dim = c(5L, 5L), x

Dear All, before its latest version my package had 'Imports: Matrix' in its DESCRIPTION file, but it did not import anything in NAMESPACE. Rather, some functions explicitly loaded Matrix, as they needed. The reason for this was that importing Matrix is really slow, and only very few igraph functions need it. (I guess Matrix is slow because of the many registered names, but that is another

Venables and Ripley (2000) R Programming (Springer, sec. 5.1) and Chambers (1998) Programming with Data (Springer) describe functions such as dumpClass and hasSlot that I can not find in R 1.9.1 for Windows nor in the "R site search". What do people use for similar functionality? Also, what resources have people found useful for learning about S4 classes, other than these 2

Hi, I am a bit unsure about using imports in packages and have a few questions. I'm sure the answer to some of these is 'it depends', but I'm interested in what others think and 'best practices' when this is the case. 1) If I use an import or importFrom declaration in a NAMESPACE, should I also qualify the package in calls to the imported function (e.g.

I have a question about what to do in the following situation (please bear with the setup): Package A defines an S4 generic 'foo' and as well as S4 methods for 'foo' and has exportMethods("foo") in its NAMESPACE file. Package B defines another method for 'foo' for class "bar" and has importFrom(A, "foo") exportMethods("foo")

I have been retooling an S4 class definition to include another slot and have found that the methods::validObject function (defined in methods/R/SClasses.R) in R-devel throws an error that isn't caught internally (and thus not controllable by 'test' argument) when retrieving a non-existent slot. The offending line of code is shown below: > validObject function (object, test =

In > R.version.string [1] "R Under development (unstable) (2011-12-15 r57901)" section 1.6.6 of 'Writing R Extensions' says Note that exporting methods on a generic in the namespace will also export the generic, and exporting a generic in the namespace will also export its methods. and Note that importMethodsFrom will also import any generics defined in

Hi, I am working at adding namespace to my packages, carefully following the doc "Writing R extensions" and some threads on the web. However I cannot find clear explanation about how to best deal with the import or importFrom functions in the name space. To make it short: To declare dependencies in the description file either after Depends: (packages including functions that are

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

Hello, an S4 class "Foo" is defined with a setter, $. For several reasons, the setter calls a function, .foo.update(). However, bypassing the argument names of the setter does not work. Question 1: Why not and how can I fix this? Question 2: What is the way to define either the function or the setter to modify the original object (not returning the modified copy of it an overwrite the

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:

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 looked through the documentation and the mailing lists and could not find an answer to this. My apologies if it has already been answered. If it has, a pointer to the relevant discussion would be greatly appreciated. Creating S4 classes containing environments exhibits unexpected behavior/features.? These have a different in two ways: 1) slotName for the data: ".xData" instead of
