similar to: XML: Slower parsing over time with htmlTreeParse()

Dear List, has anyone of you experienced a significant increase in the time it takes to parse an URL via "htmlTreeParse()" when this function is called repeatedly every minute over a couple of hours? Initially, a single parse takes about 0.5 seconds on my machine (Quad Core, 2.67 GHz, 8 MB RAM, Windows 7 64 Bit), . After some time, this can go up to 15 seconds or more.

Dear List, I’m doing my first baby steps towards developing own R Packages and ran into the following problem: R CMD check mypackage works fine (no errors, no warnings) R CMD build mypackage works fine (no errors, no warnings) R CMD INSTALL –library=”C:\R\R-2.11.1\library” “something\mypackage\mypackage_1.0.tar.gz” works fine (no errors, no warnings) However, when I try loading the

Dear list, I was wondering if you could help me out in clarifying something: Is it possible to use class "ANY" in slots/fields of formal classes if you a) do not want to restrict valid classes of that field and b) if you are making explicit use of class inheritance? It seems to work in simple scenarios but produces errors when class inheritance comes into play. So I was

Dear list, I've got the following problem: In a package I'm trying to build, there exists a method for the function "as.ts()". When checking the package, R always throws the error that it cannot find a function called "as.ts". To me it seems that the package "stats" (home of "as.ts()") is not loaded during the checking process even though

Dear list, somehow I can't get the Roxygen tag "@example" to work for me. My "Roxygen-Header" of a script containing, say, a function looks like this: #' My header #' #' My description #' #' @param a Blabla. #' @param b Blabla. #' @return \code{TRUE}. #' @callGraphPrimitives #' @references #'

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and

Dear List, I'd like to set up a package repository so I can use install.packages() on it for home-grown packages. I set up an AMPP infrastructure on a windows box already, but I'm pretty lost with respect to what to do next as I didn't do any web-programming/admin yet. Could anyone recommend some r-specific tutorials or has a couple of suggestions for me? I've had a look at the

Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def

Dear list, when iterating over a set of Rdata files that are loaded, analyzed and then removed from memory again, I experience a *significant* increase in an R process' memory consumption (killing the process eventually). It just seems like removing the object via |rm()| and firing |gc()| do not have any effect, so the memory consumption of each loaded R object cumulates until

Hi there, is there a way to create a NAMESPACE file based on Rd-files (or whatever is needed in order to apply the regular expression "^[[:alpha:]]+" without(!) resorting to package.skeleton() (as this kind of interferes with roxygenize() pretty often)? Thanks a lot, Janko [[alternative HTML version deleted]]

Dear list, just to make sure that I understand 'unregistering' methods for S4 reference classes correctly: If I registered a method and want to 'unregister' (i.e. remove) this method again, objects/instance created of the respective class still feature the removed method until I do an explicit reassign ('my.instance <- getRefClass("Classname")$new()'), right?

Dear R-help, The following code downloads an html document into variable 'doc' and then stores an internal representation into variable 'html.tree'. Even if the html code is malformed, this still works which is fantastic. However, as in the example below, i do get some ouput from R in the console which i would like to suppress somehow, so i can keep my window a bit cleaner. I

Dear List, I am not really familiar with any other language than R, but I?ve heard that in other languages there is something called ?self referencing?. Here?s what I?m trying to get an answer for: Suppose there is a function that takes as its input a value of a slot of an S4 object. The function itself is stored in another slot of the SAME S4 object. Is it then possible to have the function

Thanks a lot for answering. Before I get into it, please note that everything below bears the big capture "Thanks for trying to help me at all". 1) Yeah, those examples - quite hard to satisfy everyone's needs ;-) While the one side complained that my past examples regarding this issue were not informative enough, others didn't like the more elaborated version (as seems to be

Dear List, consider the following scenario: setClass(Class = "A", representation = representation(B = "B", C = "C")) setClass(Class = "B", representation = representation(C = "C")) setClass(Class = "C", representation = representation(something = "character")) Obviously, the collation for sourcing these defs needs to be: C,

Dear list, today I stumbled across the function ?nsl()? for the first time in order to perform a hostname lookup. According to the R Reference Index (Version 2.9.1, page 1522), the function should be part of the "utils" package. However, I cannot find it in the utils package of my installation(s). I've tried the R-versions 2.8.1, 2.9.0 and 2.9.1. I'd be very thankful if

Dear list, I'm sorry to keep coming back with this time and time again, but this bug is still not fixed even though the root cause of the issue has been around for 2-3 years now. And as the number of packages that depend on XML grows, I thought maybe this deserves some wider attention. I did my best to make reproduction of the issue as easy as possible:

Hi Gabriel, and thanks for answering. I'm basically just trying to find a way to use the power of `...` in more complex scenarios and I'm well aware that this might not be the best approach ;-) Regarding your actual question: "Are you suggesting methods be dispatched based on the *contents* of ... [...]?" Yes, I guess currently I kind of do - but not on the argument *names*
