similar to: Depends, require(), autoload() and "side effects"?

I'm trying to troubleshoot a case where R crashes on Windows. It does not occur at all with my R v2.1.0 patched (2005-05-09), but happens on R v2.1.1 (patched or non-patched) in many different cases. The R v2.2.0dev (2005-07-15) also got this problem (although it won't crash on the below example). I previously reported this

Does anyone know if it is possible to add a dictionary file of known words that becomes part of the *built* package to tell 'R CMD check --as-cran' not to report these words as misspelled. I want this dictionary to come with the *.tar.gz such that it will be available regardless where the package is checked. For instance, currently I get: * using log directory

To reply to Yves Gauvreau question (Jan 24, 2001) about how to set values within function, it is possible to do without without using the "<<-" assignment operator or other nasty tricks. I had the same problem and I did a nasty workaround two weeks ago implementing the functionality of reference variables, but today I "ran into" the [R] help page for ".Alias".

Hi, I've got a version of rowMedians(x, na.rm=FALSE) for matrices that handles missing values implemented in C. It has been optimized for memory and speed. To avoid coercing integers to doubles, and hence allocate an additional 200% memory, there is one C function for integers and one for doubles. The rowMedians() implementation is currently sitting in my non-CRAN package R.native

When using the function scan(quiet=TRUE) the line numbers are printed. Example: > scan(quiet=TRUE) 1: 123 [ENTER] 2: [ENTER] [1] 123 > Is it possible to not show the line numbers? I know about readLines() but I would like to be able to use the extra features of scan(). Thanks for you help! Henrik Bengtsson henrikb at braju.com

Hi, R v2.1.1 patched (2005-05-26) for Windows crashes. The sympotoms are like "memory leakage". The patched version from two days ago crashes at a different position in R CMD check compared to todays version. A "REPRODUCIBLE" EXAMPLE: Unfortunately, I cannot create a minimal code example reproducing the crash, but here is at least a simple way to reproduce it: 1. Make

Full_Name: Henrik Bengtsson Version: rw1022 OS: Windows Me Submission from: (NULL) (216.175.126.55) When ${R_HOME}/share/perl/maketitle.pl tries to generate a TITLE that is longer than $lc-3 (=13) characters long, it repeats the package name on line two. Example: Now it generates an output like: com.braju.graphics com.braju.graphics Bla bla bla... But, I believe it should

I thought I would post an example of using R.oo with inheritance and pass by reference for future searches. With PerMore I am inheriting Person. Then I am changing an object data memeber of an object of PerMore class using pass by reference ('mimiced' by R.oo) in an object of AgeMultiplier. I change a data member in the child class and the parent class for demonstration purposes. This is

Hello (Heinrich), I did not know I could do this. It doesn't seem to be documented anywhere. Thought this would be helpful to the fraction of the community using package R.oo. Note the call of a setMethodS3 method, xOne, in the setConstructorS3. This is extremely useful if xOne (in this case) is a very complex method (that you always want to be called every time you create a new object). If I

Full_Name: Henrik Bengtsson Version: 1.3.0 OS: Windows Me Submission from: (NULL) (216.175.122.171) I realized that the title of packages in the library index when they are in a bundle is the title of the bundle and not the package. It looks like the TITLE file, which apparently is used for generating the library index, takes the value of the bundle's title and not the package's title.

Hello, How do I inherit two classes using the R.oo package. Below is kind of a silly example, but I am trying to create class PerDog from classes Dog and Person. Error at bottom. I've tried a few other ways of using extend(), but nothing seems to get me what I want. Example: setConstructorS3("Person", function(age=NA) { this = extend(Object(), "Person", .age=age )

When I run R CMD check R.oo on R v2.7.0 devel (2008-03-04 r44677) on WinXP I get the following error while testing examples: Error in match(x, table, nomatch = 0) : formal argument "nomatch" matched by multiple actual arguments Calls: setMethodS3 -> setMethodS3.default -> %in% -> match Execution halted How is that even possible with: > get("%in%") function (x,

I don't know if this is the correct forum to ask the following question; however, when I search the aroma.affymetrix discussion group, it suggested that I should posted the question to r-help. Here it goes. I followed the instructions on aroma.affymetrix trying to install the packages; following are the steps: > install.packages(c("R.oo", "R.utils"),

Hi to all members, i have a question about class inheritance and methods using R.oo package: I have the following code and it doesn't work, guess i'm doing smth wrong and there is nothing in the help. library(R.oo) setConstructorS3("ClassA", function(A=15) { extend(Object(), "ClassA", .size = A ); }) setMethodS3("print", "ClassA",

Here are some notes/observations I've done on my setup that works for me. Hopefully it will be added to some r-forge documentation/wiki. I use: Windows Vista Business SP2 32bit TortoiseSVN 1.6.7 (Build 18415 - 32 Bit , 2010/01/22 17:55:06) PuTTY v0.60 (with Pageant v0.60) I have a deprecated r-forge project ('r-oo') that I will use through out. My r-forge username is

If someone is able, can you tell me if there is a better way to do this? More specifically, do I have to rewrite all of the data members stuff and extend stuff of parent class in the child class? See below. Thanks in advance! Example 1: setConstructorS3("ClassA", function(A,x) { if(missing(A))A=15; if(missing(x))x=NA; extend(Object(), "ClassA", .size = A, .x=x

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

Hi R-community, I'm very busy with a software project which I would like to development completely with R.oo. Many of the object oriented aspects that I already know from Java development seems to be in place with this library. But...there is something that I'm really missing... *the super method call* Just a little example that shall demonstrate what I mean: Image we have the following

Hi, Gordon Smyth brought the following problem to my attention. PROBLEM/"BUG": Using R v1.9.0 alpha for Windows and the latest Rtools from Brian Ripley you get the following problem trying to R CMD build a package (or a bundle); >R CMD build R.basic * checking for file 'R.basic/DESCRIPTION' ...
