similar to: loadings generic?

I have a generic function test.equal <- function(obj1, obj2, ...) UseMethod("test.equal") however, the only argument that specific methods use is "fuzz" so I would like to change this to test.equal <- function(obj1, obj2, fuzz=???) UseMethod("test.equal") The problem is that some methods use slightly different default values for fuzz than others. How should

I've been trying to build a bundle with the R-devel snapshot from yesterday. (Yes I know it is unstable and just tell me if I shouldn't be trying to do this yet.) It is failing with the message tar : /dev/rmt/0 : Permission denied It happens after "removing junk files" and just after the message "building dse_2000.9-1.tar.gz" It looks to be coming from the line in

What is the Rd file alias and usage syntax for an S4 assignment method? I have been trying variations on \alias{TSdoc<-,default-method} \usage{ \S4method{TSdoc}{default}(x) <- value but so far I have not got it right according to various codoc, etc, checks.

I've noticed that the arguments and result list of prcomp in the mva package (with 61.1) are not quite the same as in the Blue Book and in Splus. Is this intentional or can I change it? If I change it who should I send the code to? Paul Gilbert -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read

I had a couple of problems getting R 0.90.0. In case anyone has similar problems, I though I would mention them. 1/ I can't use "ftp cvs.r-project.org" from either home or work. The ftp service does not seem to be available. Perhaps this is intended. I only discovered it because I thought the file I got through Netscape might be corrupted. (I don't understand why Netscape

Something has changed in the S4 default for coercing. Am I now suppose to use setAs, or is there something else I should do to make this work: R version 2.7.0 (2008-04-22) .... > require("methods") > setClassUnion("OptionalPOSIXct", c("POSIXct", "NULL")) [1] "OptionalPOSIXct" > setClass("TSmetax",

One of the functions I would like to clean out of my syskern package is a program to send mail. This is a common feature other programs (e.g. bug.report) may use so I would like it to be included in R/base. I will volunteer to do this as it looks like a fairly straightforward dissection of bug.report but I have some questions: Has anyone done this already? Is "mail" a good name or

I was hoping fatal: relocation error: symbol not found: pow_ii: referenced in .../dsefor.so would disappear in R 0.6x, but it has not. I believe this is suppose to come from the f2c lib, but I seem to need just a couple of routines: nm -u dsefor.so Undefined symbols from dsefor.so: .umul pow_dd pow_ii pow_ri For my own purposes I could compile with fortran but that makes it much

The documentation for diff says: If `x' is a vector of length `n' and `differences=1', then the computed result is equal to the successive differences `x[(1:n-lag)] - x[(lag:n)]'. ...

I'm trying to do cvs -d :pserver:anoncvs@cvs.r-project.org:/home/rcvs/src login and I get "authorization failed...rejected access" with the previously advertised password (anoncvs). Has the access been changed or is anyone else having this problem? I'm not very familiar with cvs so I may be making some mistake. Paul Gilbert

Looking into several different parts of R../src/library/base/R/*.R has led me to the conclusion that quite a bit of code doubling could be saved by using the following two functions whose naming philosophy is derived from that of NROW() & NCOL(): COLNAMES <- function(x) if(is.null(n <- colnames(x))) paste(seq(length=NCOL(x))) else n ROWNAMES <- function(x)

o .Platform$OS.type is standardized to be `unix', `mac' or `windows' However, machine() still returns "Unix" rather than "unix". (I'm not sure what it returns on other platforms. Should I be thinking of machine() as standardized already, or is .Platform$OS.type the preferred standard way to check this? Paul Gilbert

When I configure and make R-devel in a directory other than the one where I keep the source, there are a few top level files which are not copied to the build directory. The ones I use are VERSION and date-stamp, to help keep track of what I am testing. Paul Gilbert

Perhaps this is not a bug but rather my misunderstanding of lty and col. I would like to generate a legend for plots as follows: par(mfcol = c(2, 1), mar = c(5.1, 6.1, 4.1, 2.1)) matplot(t(matrix(1:8,8,20)), type="l") par(mfg = c(2, 1, 2, 1)) box(col = 0) # Rbug workaround. Thanks Martin legend((par()$usr)[1:2], (par()$usr)[3:4], as.character(1:8), lty=1:8, col=1:8,
