similar to: Documenting different OO-aproaches in R as a package?

Hello R list members, I have a good object-oriented programming and software engineering background (mostly Java) and know some R. I'd like to learn more about functional programming concepts and its support and application in R. Do you have any recommendations (books, links etc)? I read (and like) "Programming in Scala" (Odersky) and just ordered "Funktionale

Hello,   Does anybody know if the OOP module (Chambers & Temple Lang) is going to replace the the S4 (and the S3) class system? http://www.omegahat.org/OOP/oop.pdf Cheers!! Albert-Jan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public

Hello,   ###  I created two classes "A" and "B". "A" is the superclass of "B".   setClass("A", representation(s1="numeric"),prototype=prototype(s1=8)) setClass("B",contains="A",representation(s2="character"),prototype=list(s2="hi")) myA=new("A") myB=new("B")   ####  I created

I have inputs to a function which are changing all the time - I pull these values from the internet. I then apply a function to the values. What I'd like to do is automate the process so it runs every one minute and adds the output of the function as a new element of a vector. Pseudo code: at Start time: input1_t0, input2_t0, input3_t0 function(input1_t0, input2_t0, input3_t0)

Hi, I am wondering if there is any convenient way to comment out an entire region of a Sweave file which comprises R and Latex code. Currently I'm doing it for the R and Latex parts separately or transfer the unwanted part into a different file. But both are not great solutions. (I am doing this when updating old files and debugging) Is there a way to do this with an equivalent of

Hi, I would like to receive help for the following matter: If I'm dealing with a numeric vectors containing increasing elements. i.e. a<-c(1,2,2,2,2,3,3,3,4,4,4,5,5,6,7,7,7) There exist an efficient way to obtain an vector that indicates the position of the changing element of "a"? In this case it would be something like: index<-c(1,6,9,12,14,15) usually I'm used

I'm experimenting using R as a report writer. I'm told LaTex is the destination for my quest. But ?latex() gives me an error. The package manager does not have it. The package installer can't find it. Where is it? It amazes me that there's not a built in "report" function that can produce the same kinds of reports that every report writer and data analysis software in

In order to get an OpenOffice configuration that is closer in compatibility with MS Office 2007, I removed the standard OO in 5.4 via yum and installed the latest (3.2.0) from OpenOffice.org. Ran that config for many months without a problem. However, when I allowed the upgrade to 5.5, OO broke. I finally had to remove all traces of OO 3.2.0, and start over. That worked...until yum tells me that

Hi all, I recently started seeing zfs chattiness at boot time: "reading zfs config" and something like "mounting zfs filesystems (n/n)". Is this really necessary? I thought with SMF the times where every script announced its'' existance had gone (and good thing, too). Can''t we print something only if it goes wrong? Michael -- Michael Schuster Recursion,

Hi List, I've set up a CRAN-like repository (not a CRAN mirror) on the local filesystem (this will change to http in the future). R has been told about this repository using the following entry in R_HOME/etc/repositories: PMR2 PMR2 file:///Users/arbeit/Documents/clarin/Open_Science/PMR2/ TRUE TRUE FALSE FALSE Now I expected download.packages(), install.packages() etc. to look for

Hi, Being relatively new to OO programming and not so old on R, I noticed the possibility to do OO programming in R. But it seems there is two "paradigms" S3 that seems the old one but is the one used in the R.oo package and S4 which seems more recent As a starting point, which one is best to use? Is R.oo useful? what are the main difference between the two? Any feedback

Can someone show me how to modify one (R.oo) class's object inside another (R.oo) class's method? Is that possible with the R.oo package? A quick example or reference to an example would be outstanding... Thanks, Ben [[alternative HTML version deleted]]

The first patch restricts passthrough parameters to ones matching "os-*". This was how it was documented, but not how it was implemented. The second patch is the same as v2 here: https://www.redhat.com/archives/libguestfs/2018-November/msg00187.html Rich.

There are different way to make R classes. I know R.oo and S4. I'm wondering which one is the current popular one. Which one is current recommended when make new R packages? Thank you!

Dear R.oo package users, while testing some functionality of the R.oo, I found that during the first construction of a object from a class, the constructor is twice called, but only one object is finalized. In all subsequent creation processes, the constructor is (expectedly) called once. Here some example code: library(R.oo) setConstructorS3("Test_class",function(val) {

Hi! I have a question concerning the :interactive Callback from the link_to_remote function. Quote from the API: "Called when the user can interact with the remote document, even though it has not finished loading." What is the exact status of the application on "interactive" - How can a user interact with the document if it''s still loading... Thanks Stefan

Hello, My name is Ion Andronache and I am a candidate for a doctor's degree on geomorphology in Braila, Romania. I would like to ask for some advice. I would like to make an analysis on the Danube's flow capacity and to determine the circles and periodicity using the Schuster system. I understood that your soft can do these operations but I don't know how. Would you be so kind to

A smaller change than v2, we simply generalize the ability to pass through flags to the underlying openstack command, allowing the --insecure flag to be specified directly. Rich.

Hi all, I'm trying to do some object-oriented programming in R using the R.oo package. Right from the start I encountered a strange (at least for me) problem. I define a new class/constructor based on the R.oo documentation. However the first attempt to create an object fails: === Code: === library(R.oo); setConstructorS3("MyClass",function(param) { print(param);

Dear, I'm looking for some examples on OO programming in R. I have the programming manual with explanation on UseMethod and NextMethod but I miss some practical examples to get me going (I hope). I searched the web but could not find a good independent tutorial on this. Any suggestions are welcome, Kris -- ------------------------------------------------------------------------
