Hello, If the signature of a method defines which generic it implements then I'm confused about why this minimal example I invented won't work : setGeneric("myFun", function(rs, ...){standardGeneric("myFun")}) setGeneric("myFun", function(cs, ...){standardGeneric("myFun")}) setMethod("myFun", "numeric", function(rs, colour =

Hi, I have written a package that contains many s4 generic functions and associated methods. I am having a lot of trouble getting R to build the help pages for these generic functions without reporting, "missing link(s): ~~fun~~, which means that it cannot find the appropriate function when code in the example section of the help is run. Right? After some playing around I can get it to

Dear List, I am not really familiar with any other language than R, but I?ve heard that in other languages there is something called ?self referencing?. Here?s what I?m trying to get an answer for: Suppose there is a function that takes as its input a value of a slot of an S4 object. The function itself is stored in another slot of the SAME S4 object. Is it then possible to have the function

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I am writing simulations in R, and quite regularly, I have to save lists and objects to HDD and load it later again. So I am wondering: why is there no function to write lists (and S3, S4 objects) onto HDD WITHOUT keeping the name? What I mean is: For data.frames I can use x <- data.frame(x = runif(10)) write.table(x, "x.txt) rm(x) y

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, how can I automatically access the functions that I loaded into a separate environment? > save(A,B,file="myfun.r") > load("myfun.r",envir=(ENV<-new.env())) > ls(ENV) [1] "A" "B" ?"[" turned up that I can access the functions via > ENV$A function () { } > ENV$A() NULL Now, how

Hi, (sorry for the wall of text; the issue here appears to be rather complicated) I'm seeing a somewhat strange case where checking whether an S4 object inherits from a parent class defined from another package with 'inherits' fails if that object is materialized through a call to 'load'. That's a mouthful, so I've put together a relatively small reproducible example

Dear developers. Have spend just 1 h searching for a bug in a new version of a new version of a package. I was getting a segfault all the time. "Funny" thing - there was no error neither in the S nor in the C code. To solve the problem I had to delete the .Rdata file! What I observed. If the .Rdata file was generated while a previous release of a package was installed in the

Hi, on R version 2.15.1 (2012-06-22) (Platform: i686-pc-linux-gnu (32-bit)) sourced functions have srcref attached as an attribute. Are such data also available for S4 generics and methods? How? (See sample code below) Thank you. Bests, Renaud f <- textConnection( " f <- function(){} setGeneric('myfun', function(x, ...) standardGeneric('myfun'))

I should add one more item that may be related here -- calling 'methods:::.requirePackage' returns a different result based on whether the package namespace is already loaded or not. If the package namespace is not loaded, the package is loaded and attached, and the package environment is returned: > methods:::.requirePackage("digest") Loading required package:

Can i somehow append objects to an .Rdata file? I didn't see an option for it in the save() method. dump() won't work since i have s4 objects in there.

Hi, Why doesn't this work? setClass("test",representation(names="character")) tmp <- new("test") tmp@names <- "a" Error in "slot<-"(object, name, TRUE, value) : 'names' attribute [1] must be the same length as the vector [0] Why does this work (replace names with name)?

(Just returning from the "wilds" of Canada, so not able to comment on the specifics, but ...) There is a basic point about generic functions that may be related to the "private" class question and my earlier remarks that Martin alluded to. R (and S4 before it) allows packages to define methods for a generic function in another package. Say, for plot() in graphics. The

Hello. What happens in the following is that I create two simple functions, f and g, on the workspace. Then I replace g. When I then call f, it uses the old version of g. Now clearly, the circumstances for this to happen must be quite special and rare. But I'd say they're not pathological. It seems to require two things: 1) masked versions of f and g on a search position lower down the

Does anyone know how to use the equivalent of debug() on an S4 method? I would like R to enter the browser not for the generic function, but for the method of the class that I specify.

Hi [R-2.10.0; suse linux] I am having difficulty creating S4 objects in the data directory of a package. I want to create a bunch of simple S4 objects for use in the examples section of the Rd files. It says in R-exts that: " R code should be ?self-sufficient? and not make use of extra functionality provided by the package, so that the data file can also be used without having to load

The following program is whittled down from a much larger program that always works on Intel, and always works on AMD's threadripper with lapply but not mclappy. With mclapply on AMD, all processes go into "suspend" mode and the program then hangs. This bug is replicable on an AMD Ryzen Threadripper 2950X 16-Core Processor (128GB RAM), running latest ubuntu 18.04. The R version

Hi Guys I'm using asterisk 1.8.23.1 When I add a SIP Header from inside the extensions.conf (SIPAddHeader(Alert-Info:<http://www.notused.com>\;info=alert-internal\;x-line-id=0) ) it works fine. When I try to do the same thing from within a database table, all of the string apart from x-line-id=0 gets ignored. I've tried escaping the semicolon and not escaping it and the result is

I would like to load ApoAI.RData. During the operation of reading this data an error occurs. There is also a problem with STF file. > library (limma) > load("ApoAI.RData") Warning message: 'RG' looks like a pre-2.4.0 S4 object: please recreate it > objects() [1] "RG" > names(RG) [1] "R" "G" "Rb"

Hi, I have an RData file containing a GeneSetCollection object (Bioconductor), http://www.cs.mu.oz.au/~gabraham/c2.RData. I think it uses lazy loading because packages are only loaded when I access the object (see below) in the R console. When I try the same with Rscript, it segfaults. This happens on 2.9.0 both on Linux and Mac: Rscript -e 'load("c2.RData"); c2[1]' ***
