similar to: dumpClass, hasSlot in R?

I have been writing quick and dirty S-plus code for years, but for a recent project I took the plunge, bought Venables and Ripley's S Programming, and implemented a class library using new style classes (in S-Plus 6.0). It worked quite nicely and I am wondering about making more routine use of them. Before I make much more of an investment, I have a few questions, both factual and subjective,

Hey folks I am just investigating using Aspects for logging my main Javascript "interfaces". I don''t believe Prototype has any built in capabilities for this but I just thought I''d check and see how people had tackled this before. I am still getting to grips with core JS so apologies if this is easy or obvious.. I am Googling as we speak also.. Cheers Matt

R helpers I am getting to grips with R but came across a small problem today that I could not fix by myself. I have 3 text files, each with a single column of data. I read them in using: myData1<-scan("C:/Program Files/R/myData1.txt") myData2<-scan("C:/Program Files/R/myData2.txt") myData3<-scan("C:/Program Files/R/myData3.txt") I wanted to produce a

Good evening to all. I find myself trying to create some Thiessen Polygons, in order to finish a meteorology research. This is the script I found to create the Polygons: * * *voronoipolygons <- function(x) {* * require(deldir)* * if (.hasSlot(x, 'coords')) {* * crds <- x@coords * * } else crds <- x* * z <- deldir(crds[,1], crds[,2])* * w <- tile.list(z)* * polys

Hi all I'm trying to get to grips with this one, but just can't figure it out. I recently acquired some 2nd hand Dell Poweredge 860 servers, and noticed that they have built in remote management interfaces. So, I have setup one, and assigned an IP address to it, but have no idea on how to access it remotely. Google'ing for an answer didn't bring me more than general product

Hi, I'm just coming to grips with "for" looping etc. and have a bit of a problem: I want to generate a sequence which goes 1 2 3 4 5 6 7 8 14 15 16 17 18 19 20 21 26 27 ... i.e. 8 consecutive numbers then 5 missed then the next 8 numbers etc. I was going to do this using the seq() function but couldn't figure out how so I thought I'd try a loop: for (x in seq(1,650,13)) {

Hi all, I''m just getting to grips with rspec, and I''m trying to put together a showy demo. We''re trying to use the (plain text) stories feature, rather than the specs. I''d like to show off a fancy HTML report of the results if possible. So it seems I can do this from the spec command line tool, but I can''t make it work for a story. I''ve got

Hi I'm trying to get to grips with R and establish R as a teaching medium in my secondary school. I would like to use R to analyse text so I can produce frequency analysis of the text for subsequent examination of ciphers. I can produce code in VBA but I am struggling when writing in R to examine each character. There must be a clear method using the vectorised format of R. Furthermore,

Hi, I'm slowly getting to grips with what makes up LLVM. I intend to use it in a machine simulator, e.g. processor, clock, RAM, UART, and other devices, where the processor will be one of several. It would take a block of target instructions, e.g. ARM, and produce LLVM to simulate those on the target machine state, and then JIT them to host instructions and then execute. The peripheral

Hello,   I would like to do a meta-analysis with the package « metafor ». Ideally I would like to use a mixed model because I’m interested to see the effect of some moderators. But the data set I managed to collect from literature presents two limits.   -         Firstly, for each observation, I have means for a treatment and for a control, but I don’t always have corresponding standard

Hey! I am Mehak, final year CSE student at IIT, India. I am keen on the project: Learning to Rank Stabilisation (Letor). I completed a course in Information Retrieval, passing with the highest grade at the university. I am proficient with C++. Also, I have research ML projects to my credit. I feel I fit the requirements for the project. I am exploring the project specific page of Letor. I

Hi Folks, I''m trying to get to grips with dapptrace, running it on my Mac. Everything seems pretty straightforward, except for - of course - what I''m trying to do. I want to focus in on my code but I can''t seem to be able to output just the functions I want, i.e. user functions. The -U option gives everything. Too much of course. Leaving that blank means the

Hi, I have been trying to get to grips with GCC's specs language in order to add COFF and ELF emission options. I have noticed that the '-emit-llvm-bc' option does not appear to work at all either with -S or without, giving :- llvm-gcc: unrecognized option '-emit-llvm-bc' Also this seems by default seems for '-emit-llvm' to produce a '.o' file instead of

The byte pixies have rolled up R-2.13.2.tar.gz at 9:00 this morning. This is intended to be the final release of the 2.13 series, for the benefit of those apprehensive of putting 2.14.x into production use. The run-in for 2.14.0 starts on Monday, with a planned release on Oct 31 (The Great Pumpkin Man Release). You can get it from http://cran.r-project.org/src/base/R-2/R-2.13.2.tar.gz or wait

Hi, I could never find out what''s the difference between nginx and mongrel. All my searches say "nginx is a HTTP server ..." and "Mongrel is a fast HTTP library and server for Ruby....". For me they both mean "...HTTP server...". I kept up with this question for some time till I came across this santence from the guys at Friend for Sale: -----------------

I've got myself in a bit of a pickle trying to install the latest Samba 3.6.20-31 package from SerNet on a Debian Wheezy server. The installed Debian version of Samba was 3.6.6. It's an off-line test server, and I'm still getting to grips with Debian, so no harm done, but I'd like to know the proper procedure to install this software! What I've done is: Edited

Hi the devel list. I am adapting the package.skeleton to S4 classes and methods I would have been very proud to post a new working function on this list. Unfortunately, I do not manage to solve all the problems. Mainly - sys.source does not compile a file with setClass - dumpMethod does not exists yet In the following code, thise two problems are notified by a line ################# Still
