similar to: Documenting classes and methods: was Re: R-devel Digest, Vol 3, Issue 23

I have been writing some S4 classes and have a problem about how I might pass a signature to "c()". Take the following example: setClass("collection", representation("list", date="POSIXt")) x <- new("collection", list(1,2,3), date=Sys.time()) y <- new("collection", list(4,5,6), date=Sys.time()) obviously, I can do c(x,y), but

I'm sure that many people are in the same position as me in that they are trying to write packages and code that is vaguely "future proof". Would it be possible to get some guidance on how the R-core team see the evolution of the "base" package with regard to s4 methods. There seem to be quite a lot of inconsistencies between s3 and s4 methods and classes currently and

I am another person who has had trouble documenting S4 classes and (particularly) methods. The methods package itself is pretty cool by the way, but it is a pity that there are as yet no guidelines on S4 in the "Writing R Extensions" document. I have actually put together a guide on S4 documentation myself for the use of my own lab which is at

Okay, here's the background. Fedora Core 4, all recent updates. Using samba-3.0.14a-2. Trying to mount a remote shared folder, and sharing it for local users in my office. Using /etc/fstab to auto-mount it on bootup. Here is the /etc/fstab line that I use to do this: //share/ccc /gobo smbfs username=XXXXX,password=XXXXXX,uid=10395,gid=30038,fmask=770,dmask=770 0 0 I use winbind to

1. I'm putting together my first package that uses S4 classes and objects. I'd like to document them, but I'm not sure what the documentation should look like, and package.skeleton doesn't produce any at all for the classes or methods. Are there any good examples to follow? 2. How do I do the equivalent of debug(foo), when foo is an anonymous function being used as a method?

Has there been a recent change in the behavior of binary operators? In SparseM it was, until quite recently ok to do scalar multiplication but now, > A*4 Error in A * 4 : non-numeric argument to binary operator > 4*A Error in 4 * A : non-numeric argument to binary operator > A%*%A An object of class "matrix.csr" Slot "ra": [1] 1 1 1 Slot "ja": [1] 1 2 3

I have been building a package around a sequence of S4 classes which I have coded in separate *.R files in the "./R" subdirectory of the package. The package builds without error, but when I load it in R I get: Error in reconcilePropertiesAndPrototype(name, slots, prototype, superClasses) : Class "xxxx" extends an undefined class ("yyyyyy" I guess R is trying to

Hi, I'm developing an R/TclTk application which uses the BWidget and Tktable Tk extensions and I'm trying to make it easy to install. For now, I'm focusing on Windows users who start with nothing. I have built Tcl/Tk and Tktable for windows using Msys/MinGW. (BWidget contains only Tcl scripts so does not need building.) I have then copied Tktable and BWidget into the lib subdirectory

I am having problems getting the unz() function to work as a connection to start reading a file... z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") readLines(z,2) yields the following problems: > z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") Error in unz("c:/temp/stoxx.zip",

I am having problems porting a package to R-1.8.0 where I have complex S4 classes with slots inheriting from POSIXct. For example: > setClass("test1", representation(date="POSIXct")) [1] "test1" > new("test1", date=as.POSIXct("2003-10-09")) Error in ext@test(object) : couldn't find function "%in %" Under R-1.7.1 this worked

Hi all, Using R a as a real-time application called by Php for a website, I would like to run one R process only, which would manage user connections. For the time each user who asks for an analysis causes a new R process to start, which is not suitable in prevision of many users. R needs about 30 seconds to run the script which makes the analysis. The problem is that this waiting time is n

I have justed upgraded R v1.7.0 on Windows NT 4 and have installed the latest RMySQL (version 0.5-1)and DBI (version 0.1-5) packages. When I issue the following commands (tactfully adjusted) R just crashes and disappears, any ideas? require(RMySQL) m <- dbDriver("MySQL") con <- dbConnect(m, dbname="xxx", user="xxx", password="xxx",

Hi, The following question might come from my (deep) misunderstanding of the concepts in the package 'methods'. I have a class 'A', and a class 'B' inheriting 'A' (so defined with 'setClass' and the parameter 'contains="A"'. The class A has a method 'mymethod'. A call to 'showMethods("mymethod")' return the

It concerns trival diagonal matrices: > diag(1) [,1] [1,] 1 > diag(rnorm(1)) <0 x 0 matrix> > diag(rnorm(1),nrow=1) [,1] [1,] 0.4843697 There's an obvious work around... but I thought it was worth notifying the list.

Dear all, (please Cc) yesterday I had two bugs with btrfs and ext3 occurrences, always happening when plugging in an external USB btrfs disk. Today I had a BUG which is purely ext3 related. The last bug was with yesterdays latest git checkout.

Does anybody have a tuned Rblas.dll compiled against ALTLAS for a dual Xeon system?

I have been having problems making the recommended packages under windows NT when WINHELP is set to NO. It seems to go ahead and create the chm files and then fall over with an error. The base packages work fine. Clearly I can fix this myself messily, but I thought it might be useful feedback. Regards, John Marsland _ platform i386-pc-mingw32 arch i386 os mingw32 system

Does anybody have some simple instructions to get me going using the GNU debugger GDB under windows with R? The R Extensions manual mentions briefly debugging under unix, but I've seen seen GDB mention in the Bloodshed Dev C++ IDE so it should be possible to use it with R? Regards, John [Using R-1.8.0 under Windows NT 4.0]

My question has two parts. The first is with regard to the frame or environment in which generic functions are defined in packages. It seems as though they are defined (i.e. exist as objects) in frame 1, even when defined in a package. The following is a short example: setClass("track",representation(x="numeric",y="numeric")) plotTrack <- function(x,y,...)

Yes, lots of packages do use C/Fortran code ... it would be great if there were more packages that are "pure R" especially since the advent of S4 classes and namespaces. Is it worth suggesting that we create a designation "pure R" for packages that have no external source code and encourage more of these? Indeed, now the number of packages is so big could they be classified to
