Dear UseRs, Does anyone know when exactly the validity is checked in S4? Documentation is silent:(. Here is a small example: setClass("test1",representation(a="numeric")) setMethod("initialize","test1", function(.Object,...){ a<-runif(1) ## here slot "a" is initialized ## callNextMethod(.Object,a=a,...)

Can someone explain what the problem is when I use the generating function? And how to get debug() to stop in the Superclass initialize method? ---- source ----- setClass("Superclass", representation(id = "character"), contains = "VIRTUAL") setMethod("initialize", signature(.Object = "Superclass"),

Hi, But "any" rises some other problems well known from S3. One has "any" for "free" in S3. You don't need S4. . But I know how "if" polluted functions look like in S3. They are hard to understand and to maintain. Hence I am quite happy to use S4. Type-checking is usefull if you program with data. Also if you are on the "C side" of the

Hello all, It appears that for the simplest of S4 objects, z+1 does not equal 1+z. Presumably this is a bug, as 1+z seems to make a malformed object (at least malformed as an input to str). Thanks, Robert > setClass("test", representation("vector")) [1] "test" > z <- new("test", 1) > identical(z+1, 1+z) [1] FALSE > str(z+1) Formal class

Hi, I have two example packages, test1 and test2, where the only code in them is: setGeneric("predict", function(object, ...) standardGeneric("predict")) (get them from http://www.cs.mu.oz.au/~gabraham/test1.tar and http://www.cs.mu.oz.au/~gabraham/test2.tar) The difference between them is that first does not have a namespace, and loads fine. The second has a namespace

Hi, Say I have two packages, test1 and test2, that both define the generic method train (identical definition), and each has a specific train method for a different S4 object (foo and bar, resp.) I want to be able to call train(foo, x, y) and train(bar, x, y), which doesn't work since test2 masks test1, as seen below. The two solutions I can think of are to a) prefix train,

Dear R, I have two R instances running at the same time, say instance A and instance B. Is there a simpler way to pass the data in A to B? More precise, I have a stupid example: In instance A, I am running a function "test1" test1 <- function (x1) { x2 <- sin(x1) return(x2) } In instance B, another function "test2" test2 <- function (x2) { x3 <-

Dear UseRs, A simple class inheritance example: > setClass("test",representation(a="numeric")) > setMethod("initialize","test", function(.Object,x,...){ print("Initialization!!!") callNextMethod(.Object,a=x,...) }) > new("test",x=23) [1] "Initialization!!!" An

Hello, I have a question concerning "setClassUnion". I'm working with R 2.0.0 Patched (2004-10-06) on windows 2000. I tried to use "setClassUnion" in a package I am currently working on. The situation is similar to the following example: The DESCRIPTION file has entries: Depends: R (>= 2.0.0), methods Imports: methods LazyLoad: yes The NAMESPACE file has

Hi, Starting with ordinary vectors, so we know what to expect: > mapply(function(x, y) {x * y}, 101:106, rep(1:3, 2)) [1] 101 204 309 104 210 318 > mapply(function(x, y) {x * y}, 101:106, 1:3) [1] 101 204 309 104 210 318 Now with an S4 object: setClass("A", representation(aa="integer")) a <- new("A", aa=101:106) > length(a)

Alight, I've been working on this for too many hours straight. Any help would be much appreciated! (I posted this online to linux questions, it could be easier to read on there... http://www.linuxquestions.org/questions/linux-server-73/samba-and-openldap-authentication-issues-637647/) The problem is users created in smbldap-useradd can not login, unless they also are a local user. for

Hi, I have a userdb file set up in passwd-file format containing the following entries: >doveadm user test1*test2 at test.com test1-test2 at test.com test1?test2 at test.com test1 at test2@test.com test1%test2 at test.com I can access the 1st entry (no special characters) no problem: >doveadm user test1-test2 at test.com -f home /var/vmail The 2nd entry (using UTF-8 encoding)

Hello all, after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn?t work anymore. Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately. I read the related wiki pages again and tried to

The default prototype object for an S4 class up to now has been a zero-length list (nothing else worked). This is wrong in principle, because it makes the objects look like vectors to low-level C code, and they should not. It may also be the cause of some inefficiency. A new low-level type has been added for these classes. It's currently available in the r-devel version, but not turned

I posted the question below about a month ago but received no response. I still have not been able to figure out what is happening. I also noticed another oddity. When the data part of the object is a multivariate time series, it doesn't show up in the structure, but it can be treated as a multivariate time series. Is this a bug in str? > setClass("tsExtended", representation =

Hi, Background : I am using rsync to push/sync FTP uploaded files from master server to slave servers. On slaves the full directory path of each file doesn't exist so rsync is unable to sync it and there a no options in rsync to do something like "mkdir -p/install -D -d" on destination before sync file. N.B. I don't want to do a full sync of the root/home directory every time a

Hi All, I installed OpenSUSE 11.0, updated samba server to 3.2.4 version. Added two users in linux and samba with user names "test1" and "Test2". (Please note the capital letter in Test2).

Dear R Group I was trying to use the triangle.test function in SensoMineR and strangely i encounter a error in the output of preference matrix from the analysis.
