Hi, A lowess method is defined in our package for one of our S4 classes. To explicitely define the generic this is being used if (!isGeneric("lowess")) setGeneric("lowess", useAsDefault = lowess) This works fine for many other methods inherited from various R packages. In this case a warning is issued in R CMD check: * checking R code for possible problems ... NOTE

Hello, I am trying to draw a key inside a single panel in a lattice xyplot. The panel function uses panel.number() to use a slightly different style for one of the panels. Once inside than panel I am using draw.key(list(text=list(lab='catch'), lines=list(lwd=c(2)), text=list(lab='landings'), rectangles=list(col=rgb(0.1, 0.1, 0, 0.1)), x=0,

Dear all, After installing R 2.4.0, a definition of "[" for an S4 class has stopped working as the default for drop in the generic, TRUE, appears to override the default in the method The method is defined for demonstration purposes as setMethod("[", signature(x="FLQuant"), function(x, i="missing", j="missing", k="missing",

Hi, I recently ran into this problem. I couldn't find any mention of it in the setClass documentation. setClass("Foo", representation(file = "character")) setMethod("initialize", "Foo", function(.Object, file) { print(file) }) setClass("Bar", contains = "Foo") And the error: Error in print(file) : argument "file" is

Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

Hi,   I'm reading up on S4 classes *). There seem to be at least two ways of input validation: setClass() (using the 'validity' argument)  and setValidity(). Is it a matter of taste which function is used? Or should more complex validation code better be put in a setValiditity call? *) A (Not So) Short Introduction to S4 Object Oriented Programming in R V0.5.1 Christophe Genolini

Generally you'd use file() to open the file, then use readLines(), say inside a while() loop to read one `chunk' at a time. However, your example looks a bit strange. The possibility of empty line makes it a bit more complicated, by that last couple of lines seems to suggest that you could have a line of data follow by another line of data without variable label. If that's true, I

Hi all, I have a self written likelihood as a model and functions to optimize and get fitted values, confidence intervals ect. I wonder if there is a way to define a 'class', or a 'model' (or a certain object)? so that I can use 'summary' to produce a summary like it does for a lm object. Also, it should be able to use 'predict' and 'plot' and other

Hi Suppose I have an S4 class "foo" and a validity checking function ".checkfoo()": setClass("foo", representation=representation("numeric")) setValidity("foo" , .checkfoo) is fine; in my application, .checkfoo() verifies that a bunch of necessary conditions are met. But .checkfoo() is very time consuming and I want to give users the option

Dear all, I am experiencing some problems with S4 method overloading. I have defined a generic for graphics:plot, using setGeneric("plot", useAsDefault = plot) and with importFrom('graphics', 'plot') and exportMethods('plot') in the NAMESPACE file of pkg A. I then proceed to define a method for signature c('myS4class', 'missing'). This works

Hello, I am about to move all of my modelling work into R, and I have been investigating the present state of MCMC and Bayesian methods in R. Following a thread on the mailing list in 2000, I have looked at mcmcpack and Hydra. Three years down the line, is there anything new in this area? I have used both MCSim and WinBUGS in the past. The first one seems promising, but is too focused towards

Hello, I am trying to use Yan and Rossini's Makefile for cross building Windows versions of R packages in Linux with R 1.9.0. When compiling R with the mingw tools I get an error about expm1 being undeclared when first found at src/main/arithmetic.c:1019 If I fiddle a bit with it later on I also get errors about log1p bein undeclared. Any idea what should I look for? I am using R 1.9.0 in
