Dear all, I'm trying to install lme4 (after having installed R 2.4.0 from source, and having installed the latest Matrix package). lme4 fails with the following message: pedigree.o definition of _lme4_xSym in section (__DATA,__common) pedigree.o definition of _lme4_ySym in section (__DATA,__common) make: *** [lme4.so] Error 1 ERROR: compilation failed for package 'lme4' ** Removing

Hello R-Team, May you help me to post a 'S4-creating Package Problem'? Thanks already now for supporting. The problem sounds like: Hello R forum, while compiling my R-package these 'Warnings' occur: ...

In my package, I create a new method for plot with the following signature: setMethod("plot", signature(x="marrayNorm", y="formula"), plot.ma) where marrayNorm is a class defined in the marray package. After building and installing my package, I get the following warnings when I load my package (with library(maVis)): Warning messages: 1: In the method signature

I'm seeing weird issues in methods initialization, i.e. loading marrayClasses loads Biobase, and when explicitly done, as in library(Biobase) library(marrayClasses) is fine, but when Biobase is loaded via a require statement in marrayClasses' .First.Lib, I end up with: Warning message: In the method signature for function "coerce", class "exprSet" has no

Hello, I have a simple class that looks like: setClass("statisticInfo", representation( max = "numeric", min = "numeric", beg = "numeric", current = "numeric", avg = "numeric", obs = "vector"

after this setClass("A") setGeneric("bar", function(x, y) standardGeneric("bar")) setMethod(bar, signature(x="A", y="A"), function(x, y) {}) setMethod(bar, signature(x="A", y="ANY"), function(x, y) {}) the method for signature c("A", "A") contains package information > str(getMethod(bar,

I am trying to get a script to start automatically when I run the GUI version of R version 1.9.0, started from a .bat file (WINDOWS), but I'm getting strange errors In version 1.8.1 I was able to run a script automatically by copying the script into the file .Rprofile and running Rgui from a .bat script, but in version 1.9.0 I'm getting errors like: Error in inherits(x,

This seemed too advanced for r-help and is related to the recent discussion of character vectors in dataframes. Following Brian Ripley's most excellent advice, we are moving to a world in which character vectors in dataframes are always of class AsIs. The cool way of doing this seemed to be the following: > cat(c("x", "y", "z"), file = "test.txt",

Hello to the list Some days ago, I placed a question on this maling-list and received an answer from Martin that I tried to follow. Unfortunately, I am still puzzled by the next step. I spent the whole Week-end in gathering information from the net. Some of them are almost contridtcory and I lack a good document to help me. So my first question would beL Is there a convenient document which

Versions 0.9975-1 of the Matrix and lme4 packages will soon be available on CRAN for use with R version 2.4.0 or later. Purpose of the packages: The Matrix package provides S4 classes and methods for sparse and dense matrices. The lme4 package provides functions for fitting and assessing linear or generalized linear mixed effects models (also called multilevel models). Like the Matrix package,

How can I extend the signature of a generic function, because the following example is unclear for me. setClass("A",representation(data="numeric")); setGeneric("func",function(obj,...){ res <- standardGeneric("func"); res at cal <- match.arg(); return(res); }); func1.A <- function(obj){ print("A"); return(); }

I am new to using S4 methods and have run into this problem (on Windows XP using R 2.4.1): I am writing a package in which I use the graph package.
