similar to: ReferenceClasses examples {method}

Dear help, 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 with :

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

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

I am running R 2.0.0, GOstats 1.1.1 and GO 1.7.0, and when I use the function GOHyperG, I have the following error: w1<-as.list(hgu95av2LOCUSID) w2<-unique(unlist(w1)) set.seed(123) myLL<-sample(w2,100) xx <- GOHyperG(myLL) Error in mget(x, env = GOTERM, ifnotfound = NA) : recursive default argument reference In fact first I tried this function with my locusId ' list (with

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

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

hello it seems like this question has appeared a few times with no answer: how do you get rails to issue ''write'' statements (ie ''CREATE/UPDATE'') to the database without committing each time? I tried setting ActiveRecord::Base.connection.begin_db_transaction before calling any action on my object, but as soon as myObject.save or myObject.update is called,

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 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

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

Hello! I am optimizing my code in R and for this I need to know a bit more about the internals. It would help tremendously if someone could link me to a page with O()-complexities of all the operations. In this particular case, I need something like a linked list with O(1) insertLast/First ability. I can't preallocate a vector since I do not know the final size of the list ahead of time. The

Dear list, I don't know what's the correct term for this in the OOP context, but is it possible to "clone"/copy an instance of a reference class (say 'a') so that I get an *autonomous* second instance 'b'? Autonomous in the sense that changes to 'a' do not affect 'b'. I know that this is somewhat against the pass-by-reference paradigm, but the

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
