ReferenceClasses examples {method}
Dear r-devel-list, dear John Chambers, I'm trying to learn OOP-possibilities in R and I was going through the documentation 'ReferenceClasses {methods}' (great work, by the way...). Reading associated Examples, something bothers me : it seems to me that there are errors in 'edit' and 'undo' methods. I think that : - 'undo' should update 'edits' field

Class generator functions for reference classes
As of rev. 61035 in r-devel, setRefClass() now returns a generator function, as setClass() has done since 2.15.0. The convenient style is now: mEdit <- setRefClass("mEdit",......) xx <- mEdit(data = xMat) instead of xx <- mEdit$new(data = xMat) The returned object still has fields and methods accessible as before. See the "Value" and "Reference Class

Interfacing a C++ class
Hello Apologies for cross-posting, the discussion should (if) go to R-devel, but I also want to reach the rcpp-devel people. My C++ class FOO is a module available through Rcpp, and it works fine and is -- so far -- bug free. With trying to further develop my R package, I thought it was a good idea to interface my C++ workhorse FOO with an S4 class Foo. After some long and not always insightful

Object-oriented programming (OOP)
Hello everybody, please excuse my bad English. I am Alfredo Naime and I'm from to Venezuela. I want to make a lib with tools for simulation (queues, inventories, factory, etc.) using object-oriented programming (OOP). You have any manuals on the handling of data types, classes, inheritance, etc. in R with examples and how to make a R lib. Thank you, very much. Alfredo

Nomogram with multiple interactions (package rms)
Dear list, I'm facing the following problem : A cox model with my sex variable interacting with several continuous variables : cph(S~sex*(x1+x2+x3)) And I'd like to make a nomogram. I know it's a bit tricky and one mights argue that nomogram is not a good a choice... I could use the parameter interact=list(sex=("male","female"),x1=c(a,b,c))... but with rcs or pol

S4-classes: Assignment of values to slots by reference
Dear R-users, I am working on a project that uses S4-classes. At some point I encountered the problem - well known to R - that I have to pass 3 different objects to a function, that should modify several slots of them and of course there is no passing by reference in R. Then I read this thread by Steve Lianoglou: https://stat.ethz.ch/pipermail/r-help/2010-August/250468.html, which offers from

How to debug reference classes?
How do you debug methods of a reference class? I've been using mtrace, which is excellent, but i cannot figure out how to mtrace a reference class method. Maybe there is some other way to debug these, for example with ordinary trace? for now i am only able to use options(error=recover), which is not giving me idea where exactly in the code i am once i am stopped on an error. -- View this

S4 generic functions/methods vs enclosures
Apologies for asking something that is probably very obvious, i just started with S4 classes and i guess i am not finding documentation that lays out the grammar rules and gives enough examples. I understand that main method of writing a member function is to write a generic function and setMethod for this particular class. This, however, presumes that there is "virtuality" for this

"ask=F" option with plot.gam
Hello. I'd like to plot only one component smooth function of a gam model (for example the second) (library mgcv). So, I did : plot(my.gam, select=2, ask=F) But plot.gam doesn't seem to understand the "ask" option, so I can't deactivate the interactive plotting. I tried and failed by forcing it through : par(ask=F) And the "page" option of plot.gam (automatic

Reference Classes: shortcut like 'isS4' for Ref Classes?
Dear list, is there a shortcut-function to check whether a class is a Reference Class or not? There's something like this for S4 classes ('isS4(object)'), but I couldn't find anything regarding Ref Classes. Currently, I'm doing it this way, which is a bit clumsy: A <- setRefClass("A", fields=list(X="numeric")) a <- A$new() isRefClass <-

S4 Slot assignment within function
Is there a simple way to assign values to S4 slots from within a function? Doing this doesn't work: > assign_slot<-function(x){ assign("OBJECT at slot",x,envir=parent.env(environment()) } >assign_slot(x) All I get from this is a new object with the name OBJECT at slot, the slot assignment of OBJECT doesn't change. I have thought about solutions such as

Private Variables in R5-Classes possible?
Hi list, is there a way to define some kind of private Variable? I would like to prevent the user from manipulating fields on his own, in order to not destroy data structures. The problem is, that as soon as the variable exists in the environment it is accessible via t$secret_value. test <- setRefClass("test", fields=list( secret = function(value){ cat("the function was

Spectral Coherence
Greetings, I would like to estimate a spectral coherence between two timeseries. The stats : spectrum() returns a coh matrix which estimates coherence (squared). A basic test which from which i expect near-zero coherence: x = rnorm(500) y = rnorm(500) xts = ts(x, frequency = 10) yts = ts(y, frequency = 10) gxy = spectrum( cbind( xts, yts ) ) plot( gxy $ freq, gxy $
