similar to: slot(obj, "nosuch") documentation question

Hi, It's nice to be able to define S4 classes with slots that correspond to standard attributes: setClass("A1", slots=c(names="character")) setClass("A2", slots=c(dim="integer")) setClass("A3", slots=c(dimnames="list")) By doing this, one gets a few methods for free: a1 <- new("A1", names=letters[1:3])

I've fixed this and will commit soon. Disregard my dim<-() example; that behaves as expected (the class needs a dim<-() method).

Dear R experts, I have defined a class "myclass" and would like the slots to be extractable not only by "@" but also by "$". I now try to write a method for "$" that simply executes the request object at slotname, whenever someone calls object$slotname for any object of class "myclass". I don't manage to find out how I can provide this

I want to loop through slots of an S4 object and am unsure how to do so since the only way I can find to access them is individually in the form 'object@slotName'. I have guessed at a few possibilities which did not work and I have read some S4 object tutorials and things but still unsuccessful. I presume it is possible though? Any help would be much appreciated, Scott [[alternative

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

Thanks for the report. The issue is that one cannot set special attributes like names, dim, dimnames, etc on S4 objects. I was aready working on this and will have a fix soon. > a2 <- new("A2") > dim(a2) <- c(2, 3) Error in dim(a2) <- c(2, 3) : invalid first argument On Mon, Jun 5, 2017 at 6:08 PM, Herv?

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 =

I created some S4 objects that are essentially data frame objects. The S4 object definitions were necessary to verify data integrity and force a standardized data format. I am, however, finding myself redefining all the typical generic functions so that I can still manipulate my S4 objects as if they were data frames ... I have used setMethod to set methods for "subset",

Dear List, I am analyzing the home range area of fish and seem to have lost the individuals ID names during my manipulations, and can't find out how to rename them. I calculated the MCP of the fish using mcp() in Adehabitat. MCP's were converted to spatial points data frame and exported to qGIS for manipulations. At this point the ID names were lost. I brought the manipulated

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 =

R-help I have installed R 2.0.0 ( Windows) on my machine and had several 'crashes' while working on it. I have reinstalled a couple of times and still got strange behaviour from time to time(screen goes white and no prompt is printed out,,,) Last time I have reinstalled I checked the md5sum.txt (md5sum output for the setup program and went O.K) and also Md5 from which I paste a piece of

Hello, We have a user that wants to get the code coverage report for his library without turning on instrumentation for the library clients or change how they are built (only the library is instrumented). It seems like the inline member functions defined in headers are not instrumented in this case because the clients are not instrumented. The library itself does not have a copy of the inline

In the current mangling scheme for overloaded intrinsics we include overloaded type names in the intrinsic name. For example: %struct.foobar = type { i32 } declare <4 x %struct.foobar*> @llvm.masked.load.v4p0struct.foobar(<4 x %struct.foobar*>*, i32, <4 x i1>, <4 x %struct.foobar*>) Verifier checks that an overloaded intrinsic name matches with its signature.

Hi, I've been running a samba server with winbind (CentOS 7) as a member of an AD Domain (Windows 2012 R2) for several months without a problem. "Suddenly" I'm seeing the problem that the membership in newly created AD groups isn't correctly visible for some users on the samba server or only after some indefinite amount of time. I'm looking simply at the output of

I've been developing a package called foobar for a couple of years now. It has evolved through various versions, but has always contained compiled C code. Recently, R CMD check has started generating the following message [START QUOTE] R CMD check foobar_1.7.5.tar.gz * using log directory ?/home/david/foobar/package/foobar.Rcheck? * using R version 2.15.2 (2012-10-26) * using platform:

Hello lovelies, Our team is deliberating a few different options for the hierification of our modules; and wanted to poll the collective genius before making our decision. As we all know, there are certain attributes of a package which are, by default, consistent on an OS... say, the name of a package..... class foobar { include foobar::params $package = $foobar::params::package Package
