similar to: R.oo installation warnings?

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!

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);

I noticed about a couple weeks ago that my R start up script starting showing the below errors, following the line "Type 'q()' to quit R" Not sure what I did different and so far it hasn't caused major problems but kind of fear that it will. Can you please help? I also posted my Rprofile below. Attempting to load the environment 'package:R.utils' R.methodsS3 v1.2.2

Hi Guys, I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory. I googled a little bit and tried all fixes/suggestions with no success. Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

Hi, I am trying to load into R a MATLAB format file (actually, as saved by octave). The file is about 300kB but R complains with a memory allocation error: > library(Rcompression) > library(R.matlab) Loading required package: R.oo Loading required package: R.methodsS3 R.methodsS3 v1.2.0 (2010-03-13) successfully loaded.

Hello! I'm using R-2.14.2 on a Windows 7 64 bit machine and I did the following: > install.packages("rJava",depen=TRUE) --- Please select a CRAN mirror for use in this session --- trying URL 'http://cran.sixsigmaonline.org/bin/windows/contrib/2.14/rJava_0.9-3.zip' Content type 'application/zip' length 745867 bytes (728 Kb) opened URL downloaded 728 Kb package

Good Morning, I'm trying to install the rJava package on a local (work) machine and having some trouble. The following occurred in an RGui session. > sessionInfo() R version 2.13.0 (2011-04-13) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C [5]

Calling library(..., quietly=TRUE) may still output: Loading required package: <other pkg> in some cases, e.g. > library("R.utils", quietly=TRUE) Loading required package: R.methodsS3 [...] I traced this to base:::.getRequiredPackages2(), which forgets to pass 'quietly' to an internal library() call: if (!attached) { if (!quietly)

Now that we can safely return arbitrarily large structs on x86, it seems to me that fastcc, which doesn't have to conform to any preexisting ABI, should use ECX as well as EAX and EDX for returning {i32,i32,i32} rather than use sret-demotion. Any objections?

I am getting an error message, which I do not know the source to. I have a matrix SAMPLES that has preexisting rownames that I would like to change. GENE_NAMES contains these rownames. > rownames(SAMPLES) = GENE_NAMES Error in "dimnames<-.data.frame"(`*tmp*`, value = list(list(V1 = c(3843, : invalid 'dimnames' given for data frame > dim(SAMPLES) [1] 12626

Hello, I am trying to plot selected data points to a preexisting persp plot that satisfies a condition. I used the following statement - text(coords[,1], coords[,2], names(act[which(act > 8.75)]), cex=0.7) But I get all the points labeled, instead of the points that satisfy the condition specified. Is there any way to plot only the points I want? Also can this be done using

I have a server running Ubuntu natty (libvirt 0.8.8) with separate ethernet interfaces. I have created an unnumbered bridge for each interface, these are connected to an already established network infrastructure, with preexisting DHCP and DNS services. I would like to handle *establishment* of these bridges outside libvirt (via /etc/network/interfaces), but still have them defined as networks

Hello. Can someone shed some light on the copy-storage-all feature? There are many hits on google. My current questions are. 1. is it possible to do a migrate --live --copy-storage-all .... without shared storage? 2. Do i need to have a preexisting image on the destination node? 3. Is this still true: The current implementation of --copy-storage-all uses a qemu interface that upstream qemu

I have R script that i need to run in cron. Either R libraries or some .so libraries that they depend on don't get loaded correctly. Here is an example. I have a file, call it tmp.R tmp.R ========================= R --slave --args $0 $* <<EOF cmarg = commandArgs()[5] library(R.utils) b<-intToBin(cmarg) print(paste( "argument is ", cmarg, sep=""))

Okay, so now that I''m planning to build my NAS using ZFS, I now need to devise or learn of a preexisting method to receive notification of ZFS handled errors on a remote machine. For example, if a disk fails and I don''t regularly login or SSH into the ZFS server, I''d like an email or some other notification immediately of the ZFS event. Are there already ways to do

I added debuging as follows: /* no O_EXCL, existence check is via the fcntl lock */ lockfile_fd = open(lockfile_name.buf, O_NONBLOCK|O_CREAT|O_WRONLY, 0644); if (lockfile_fd == -1) { ret = errno; DEBUG(1, ("%s: open failed: %s\n", __func__, strerror(errno))); return ret; }

Dear all, I am trying represent a matrix of discrete values. At the moment I am using levelplot from the lattice package, but it seems to only work with numerical values. Is there an option in levelplot that will allow me to assign a color to a discrete value, or another package that will do the same? To clarify, with levelplot I can represent a matrix such as: [,1] [,2] [,3] [,4] [1,]
