Hello R users I have question about the time involved in list assignment. Consider the following code snippet(see below). The first line creates a reader object, which is the interface to 1MM key-value pairs (serialized R objects) spanning 50 files (a total of 50MB). rhsqstart initiates the reading and I loop, reading each key-value pair using rhsqnextKVR. If this returns NULL, we switch to the

Dear List: Sorry for posting maybe a trivial question, but I have a basic understanding problem. If I have say pack1 and pack2, two R packages, and pack2 depends on and imports pack1 fully (as in the code below), is there a way to make all the functionality of pack1 available for the global and other environments (not only for the functions called from withing pack2) by loading pack2 only? I

Hi, in approximately one months time mentoring institutions can propose projects for the Google Summer of Code 2009, see http://code.google.com/soc/ Last year the R Foundation succesfully participated with 4 projects, see http://www.r-project.org/SoC08/ for details. We want to participate again this year. Our project proposals will be managed by Manuel Eugster (email address in CC). Manuel

Given S4 methods [ and [<-, how do I write the Rd-file usage clause for the latter one? What I have now is: \S4method{[}{TimeSeries,TimeDate,missing}(x, i, j, ..., drop) \S4method{[<-}{TimeSeries,TimeDate,missing,ANY}(x, i, j, ..., value) which results in the following output: ## S4 method for signature 'TimeSeries, TimeDate, missing': x[i, j, ..., drop]

Not sure if this the right place, but I can't seem to subscribe to the rJava mailing list. Sorry for the noise. I have a jar file in the CLASSPATH variable. On running .jinit and checking .jclassPath, i can see the jar file containing the class. Yet when trying to instantaite the class, i get a class not found error. Now If if, create my own vm (see below), and then run .jinit (which will

Dear list: I am looking for a good way to create an S4 class that would extend numeric, but would allow NULL instead of data as well. As far as I can see there is no way at the moment to do that, but please correct me if I am wrong. The best solution I came up with so far was the following (it also indicates a problem of using setClassUnion with numeric as one of the classes): I define a class

Dear list: I would like to override the default way R formats plot axes with a custom method(s). Obviously I would prefer to define it as general as possible avoiding writing a custom method for each individual class where possible. The plot.default method (and I assume other methods as well) calls Axis(...) to produce the axis layout depending on data. In this sense it seems reasonable to

Add the following to example section of a dot-Rd manpage: ## :WHY: The following kills R CMD check but runs fine on console. foos <- c("aaa", "bbb", "ccc") cat(sapply(foos, function(foo) { sprintf("name: %-18s upper: %s\n", foo, toupper(foo)) }), sep="") R CMD

Hello R-devel, I want to write extensions for R in C (maybe C++ and Fortran later) and it works fine, but there is one problem, which I cannot solve (in my view). I want to handle a matrix from R in C. For arrays there is "as.double(...)", but nothing for a matrix. I searched a while, but didn't find something. Last I looked at the source code of e1071 and of the core itself and

Hi, I have two example packages, test1 and test2, where the only code in them is: setGeneric("predict", function(object, ...) standardGeneric("predict")) (get them from http://www.cs.mu.oz.au/~gabraham/test1.tar and http://www.cs.mu.oz.au/~gabraham/test2.tar) The difference between them is that first does not have a namespace, and loads fine. The second has a namespace

Hi All, I have an asterisk box on my DMZ, and I'm using a PF for my firewall, I can make a call but some reasons I have a dead air. Any Ideas? below are my rules... ext_if = "bce0" int_if = "bce1" altitude = "172.16.1.0/24" #### machines #### vbox = "172.16.1.1" uci = "172.16.1.4" voices = "203.172.x.1" ipc =

Dear list: working with date/times I have come across a problem that ISOdate and ISOdatetime are too slow on large vectors of data. I was surprised just until I looked at the implementation and the man page: "ISOdatetime and ISOdate are convenience wrappers for strptime". In other terms, they convert data to character representation first in order to create a POSIXlt object that is then

Dear list, I am trying to write a package for simulating meioses in R. We defined a class 'haplotype' which contains the basic units of our simulation: setClass("haplotype",representation(snp = "numeric",qtl = "list", hID = "numeric",phID0 = "numeric",phID1 = "numeric"),

Hello, I've been using samba to share files on a Redhat server within a windows NT domain. Recently, security policies in the domain have changed, and security signatures are required for the LanManServer and Rdr services. Now that this has been deployed, I get an error when I try to connect to the SMB shares on the Redhat server from Windows hosts saying "account is not authorized to log

Hi all, I'm posting this here as it discusses an issue with an external C library. If it would be better in R-Help, then I'll repost. I'm using an external library which I've written, which provides a large set of data (>500MB in a highly condensed format) and the tools to return values from the data. The functionality has been tested call by call and using valgrind and works

Following my previous post on S3 method despatch, I put debug messages in the code of Axis, Axis.default and plot.default in graphics/R/axis.R and graphics/R/plot.R to print the class of x, at and y on plot. After recompiling R, what I see is that x *lost* its class attribute (at least for classes not known to 'graphics') in Axis, called directly from plot.default and this could be the

Dear List, I'm struggling with the signature writing cbind/rbind functions for a S4 class. First of all, I'm very happy that it is now possible to dispatch on ... I follow the example for "paste" in ?dotMethods, which works as far as this: ### start example setClass ("cbtest", representation = representation (data = "data.frame"),

Hi all: since about a month we encountered a problem with R -e command: spaces in the "command" of R -e "command" are no more tolerated. This same issue affects 2.11 patched (05-05-2010), 2.10.1, and current devel (at least the one of two weeks ago). (I skip the mid of the printouts, replaced with ...) * R -e "message('aaa aaa')" ARGUMENT

Hello I am writing a replacement method for an S4 class and want to pass an additional argument to "[<-"() along the lines of "["()'s "drop" argument. Specifically, I have an S4 class, call it "foo", with a slot 'x' that is a vector and a slot 'NC' that is a scalar. I want to be able to pass a Boolean argument to the

Hi. I am running SAMBA 2.0.7 on HP-UX 11.00 and HP-UX 10.20. I have tried adding the MultipleUsersOnConnection registry key onto my Microsoft Windows NT Server 4 Terminal Server Edition servers, running with Service Pack 6. After I make this change in the registry and reboot my WTS servers all my samba connections from the servers are still being made with one process instead of being split
