similar to: variable names when using S3 methods

Hi to all Authors@R: c(person("fooa","foob", role = c("aut","cre"), email = "fooa.foob@fooc.de"), person("foo1","foo2", role = c("ctb"), email = "foo1.foo2@foo3.de")) Author: fooa foob, with contributions from foo1 foo2 using r CMD check --as-cran .. (R 3.1

Hi, I am absolutely new to LLVM. Currently reading through documentation and the C-API (which i want to use). As i am working on Windows, i was curios on how to specify an import which links to a function exported by a dll. The DLLStorageClass seems to be the wy to go, this seems clear. But after declaring a function for import, how do i specify the DLL the function is included in?

I want to call summary on a mer object (from lme4) within my package but I can't seem to get the namespace to import the necessary method. I've simplified my package to this one function: --------------------------- ss <- function(m) { summary(m) } --------------------------- And my namespace file looks like this, where I've attempted to follow the instructions in "Writing

Hi, I was trying to remove some old code that handles ReturnInsts with more than 1 operand -- see attached patch -- when I stumbled across test/Assembler/aggregate-return-single-value.ll: define { i32 } @fooa() nounwind { ret i32 0 } ... define [1 x i32] @fooc() nounwind { ret i32 0 } Is there really any need to handle these odd cases, where the type of the value being returned doesn't

Dear list, It seems that S4 methods defined for an S3 'base' generic are not used in 'base' functions. This can be problematic when 'base' functions start with something like 'as.matrix'. ### START R code setClass("classA", contains = "matrix", representation(realData = "numeric")) setMethod("as.matrix",

I created a type of object similar to a data frame. In some circumstances, It needs special methods for "[" and "[<-" and rbind() (but not cbind()). Then I found this in the cbind()/rbind() man page: The method dispatching is _not_ done via 'UseMethod()', but by C-internal dispatching. Therefore, there is no need for, e.g., 'rbind.default'.

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

Hi, Infinite recursion in S3 methods seem to crash R on Windows 2000 (R terminating with the ("Rgui.exe has generated errors...") message, rather than throwing an error. This happens with both Rgui and Rterm. The following toy example triggers this: myf <- function(x, ...) UseMethod("myf") myf.default <- function(x, ...) myf(x) myf(1) ...R crashes... Which I

Dear Wolfgang, I think this new behaviour is related to the following R 4.0.0 NEWS item: > S3 method lookup now by default skips the elements of the search path between the global and base environments. Your environment "myenv" is attached at position 2 of the search() path and thus now skipped in S3 method lookup. I have just noticed that

Dear List, I have the following function: coca <- function(x, ...) { if(is.null(class(x))) class(x) <- data.class(x) UseMethod("coca", x) } and a default method coca.default <- function(x, y, method = c("predictive", "symmetric"), reg.method = c("simpls", "eigen"), weights = NULL,

Hello, I am building a package that creates a new kind of object not unlike a dataframe. However, it is not an extension of a dataframe, as the data themselves reside elsewhere. It only contains "metadata". I would like to be able to retrieve data from my objects such as the number of rows, the number of columns, the colnames, etc. I --quite naively-- thought that ncol, nrow,

Dear All, In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example: myfun <- function(y) { out <- list(y=y) class(out) <- "myclass" return(out) } print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5)) myfun(1:4) # prints: [1]

I'd like to suggest that whenever there is no S3 method implementation available for a particular class, that the error message would also report the class structure of the object dispatched on. Example: foo <- function(...) UseMethod("foo") foo.ClassA <- function(object, ...) { cat("foo() for ClassA called.\n") } > foo(structure(1, class="ClassA"))

Scenario: An S3 method is declared for an S4 base class but called for an instance of a derived class. Steps to reproduce: > Rscript -e "test <- function(x) UseMethod('test', x); test.Matrix <- function(x) 'Hi'; MatrixDispatchTest::test(Matrix::Matrix())" Error in UseMethod("test", x) : no applicable method for 'test' applied to an

Hello, I just notice this: > x <- c(1:4,0:5, 4, 11) > library(pastecs) Loading required package: boot > tp <- turnpoints(x) > extract(tp, no.tp = FALSE, peak = TRUE, pit = FALSE) [1] FALSE FALSE FALSE TRUE FALSE FALSE FALSE FALSE FALSE TRUE FALSE FALSE Warning message: arguments after the first two are ignored in: UseMethod("extract", e, n, ...) >

Hi, I have a class called "spss" containing prepared info from an SPSS file. >... >class(ret) = "spss" >return(ret) The function that returns this defined in a file that I source into R. Also in that file is a function matSummary.spss. I think I ought to be able to call >matSummary(ret) to run the function, but only >matSummary.spss(ret) will work. What

Hola, Estoy tratando de crear un método S3 llamado "anthr" dentro del paquete que estoy desarrollando, cuyo argumento principal es "res" que básicamente es una lista con un solo componente. Pero si el segundo argumento llamado "oneSize" es FALSE, "res" es una lista de listas. Lo que he escrito hasta el momento es lo siguiente: anthr <- function(res,

I do not understand what your goal is here (more context may be helpful, perhaps to others rather than me). So I doubt this is what you want, but here is a guess -- no need to respond if it is unhelpful: ## test.default returns NULL if object "y" not found in **calling environment and enclosures**; ## otherwise y. test <- function(x){ UseMethod("test") } test.default
