Dear all, Maybe, I am doing something wrong, but using R-2.5.0 on my Intel-Mac, I have problems using function callNextMethod() in method initialize. I am loading the following code as file "testS4.R": setClass("baseClass", representation(myname = "character", mydir = "character", "VIRTUAL"),

Hi, I would like to use std::shared_ptr in my pass. However I'm facing a problem wrt RTTI. If I have a code like: std::shared_ptr<BaseClass> x(new DerivedClass()); ... std::shared_ptr<DerivedClass> p = std::dynamic_pointer_cast<DerivedClass>(x); It does not compile since the default RTTI infrastructure is not used by LLVM. Also, it's not clear to me if the

Dear all, Recently, there was a question to use the same method for more than one class: https://stat.ethz.ch/pipermail/r-devel/2007-March/044809.html I have a variation of this question: Is it possible to use the same function name, e.g. "myfunction" in both, an S4 baseClass and derivedClass. The method "myfunction" in derivedCalss should extend the functionality defined

Hi *, I'm installing samba4 to test purpose but I have an error. I'm following howto.txt included in samba-4.0.0tp4.tar.gz.

Hi, I''m having trouble with some STI Classes in a test. When I create a new Class of an STI derived base class the type column is not set. If I do object = DerivedClass.create!(params) then object[:type] == nil for some reason. Any ideas why this is so? I assumed rails takes care of setting the type column in STI (that''s what I read). Nico

JavaScript doesn''t (yet) have a notion of classes. Prototype.js just adds a suitable convention for implementing them. It provides a way to create a new class by extending a base class using Object.extend, but it doesn''t handle method inheritance. There are ways of doing implementing this through traversing the chain of prototypes, but I''m not sure they are

Dear Rui, Not working. I have entirely removed the column containing % but am still bootless: > head(coredata(INFYTX)) INFY Historical Data INFY Historical Data INFY Historical Data INFY Historical Data [1,] "47.26" "44.28" "47.56" "44.28" [2,] "46.30" "44.92"

(Sorry, sent the message before I finished it) Hello, everyone I have a long script that uses zoo objects. In this script I used simple moving averages and these I can very efficiently calculate with filter() functions. Now, I have to use special "exponential" moving averages, and the only way I could write the code was with a for-loop, which makes everything extremely slow. I don't

Dear members, I have an xts object: > head(INFYTX) INFY Historical Data INFY Historical Data.1 INFY Historical Data.2 2003-04-16 "47.26" "44.28" "47.56" 2003-04-17 "46.30" "44.92" "46.53" 2003-04-21 "45.82"

Isn't this like trying to tie up the horse after it has left the barn? Why not figure all this out _before_ converting to xts?

Dear all, To explain my problem I am attaching a demonstration package "myclasspkg": I have the following two S4 classes with similar inheritance: SubSubClassA <- SubClassB <- BaseClass SubSubClassB <- SubClassB <- BaseClass In R I am calling the following functions: > library(myclasspkg) > subA <-

Dear list, I have been checking my package ('analogue') using R2.13-0-alpha (details of exact svn version appended below) and the R CMD check procedure is generating an error rebuilding a vignette in the package, which raises a NOTE in the check. The log printed to screen during check shows: .... * checking re-building of vignettes ... NOTE Error in re-building vignettes: ... Error in

Dear R-helpers, It seems to me that a character zoo cannot be coerced to a numeric zoo. Below is a minimal example. Can someone tell me what I have done wrong? > z<-zoo(1:4,order.by=1:4) > coredata(z)<-as.character(coredata(z)) > str(z) ‘zoo’ series from 1 to 4 Data: chr [1:4] "1" "2" "3" "4" Index: int [1:4] 1 2 3 4 >

It''s been a few days since I posted my last two emails (of which, no one replied to) so I''ve gone ahead and coded a working slider class as well as a ''resizeable'' class that allows a user to drag and resize the element. I also linked these two together as I want to have slider behavior that can resize the resizeable element. The end result is both the

My problem is the following : I create 2 zoo objects and then I try to subset one of them using logic. indicesthatpass is a vector of trues and falses but when I send it into bckret, it returns an empty bckret. Obviously it has something to do with bckret being a zoo object and if I do the same subsctripting off of coredata(bckret), I'm confident it will work. But, I need to keep the minute

Hi everyone, ? I am trying to do a horizonplot using my own time series data. I know that there is a horizonplot function in latticeExtra, but on closer examination i think that the graph itself is slightly wrong (it displays some regions as triangles and i think they should be trapezoids, and the red regions (that are below the baseline) are displayed on top of the blue areas ? while i think

Sir, I have hit a the limits of my understanding of text / par / opar etc... I have a few related xts data frames which have multiple columns, and have written a for-loop to make a set of charts - however i do not get any margin text when i run the loop. when i test the code outside of the loop the margin text appears - however when i run the loop the margin text does not appear ... what gives?
