I'm trying to kick off some of the rust and learn some of the R packages for Rasch modeling. When I tried using the eRm package, I get item difficulty estimates for all my items accept the first (in terms of order) item. #Begin code library(eRm) r.simulation <- sim.rasch(20,100) r.data <- r.simulation$items #eRm results erm.rasch <- RM(r.data) names(erm.rasch) erm.items <-

Hi, I am running the non-parametric rasch model tests using eRm. I have a reasonably large dataset for this type of exercise (110 items, 248 persons). I run: > allb2=as.matrix(allb) > rsample <- rsampler(allb2, ctr) > t102<-NPtest(rsample, method="T10") #global test, subgroup inv and receive error message as follows. "Error in m[idx1, idx2] <- 1 : subscript out

Dear R Users, I am using the LLTM and the LRSM functions in the eRm package to do repeated measurements where there are 2 measurement points for a list of 10 items. I am trying to get ability estimates but am having trouble. I don't think that it is appropriate to use the pmat function since the person parameters are based on all 20 items. Rather, I think it would be more appropriate to

Hi, I know it's not really the place, but if anybody in the UK (or US) is interested, I'm clearing out lots of new Cisco stock... 7970G's (colour LCD), 7960G's, 7940G's, 7920G's (wireless IP phone), 7935's (conference phone) and 3550-24-PWR switches. I also have boxes of 7914's, the single-7914 foot stand and double-7914 foot stand (these are required to

don't read this. i'm a complete newbie, and i don't know how to start sending messages. if someone read this, then can answer me also how to delete a file with the console (really ashamed) y know that copy with cp, but delete??? thanks... ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del

Might seem drastic to some, but I don't feel much pain because I almost always edit my code in a file rather than on the fly at the console, and re-run it frequently from a fresh R process to check my progress.

My Dear R buddies, I'm feeling ashamed that I've been running my R program on some servers for a while but do not know exactly how R is working. The servers are chained together using Sun Grid Engine. Each node has 8 quad-core CPUs. I wonder how many cores and CPUs are used by a simple single-thread R program. Thanks a lot.

A relatively recent development that spammers got wind of is users that have username==password, with/without the domain. I am tracking numerous 1-off attempts from bots to gain access to mailboxes this way. Situation isn't made any better if you're also using dovecot as SMTP AUTH provider for I am ashamed to admit I've relayed some spam that way. Would it be possible to deny login

Cisco should really be ashamed of this product... While it is physically well constructed, and has excellent sound quality along with a very pleasant user interface, the device has SERIOUS stability issues, unless you run your network with an iron fist... Quite by accident, while configuring my Asterisk system to connect to a Cisco 7960 via SIP in a standard office PBX type arrangement, I

When I try to create a Rasch simulation of data using the sim.rasch function, I get more items than I intend #My code library(eRm) #Number of items k <- 20 #Number of participants n <- 100 #Create Rasch Data #sim.rasch(persons, items, seed = NULL, cutpoint = "randomized") r.simulation <- sim.rasch(n,k) I end up with 20 participants and 100 items, but the instructions say

OK, dumb question, and it is probably in the docs somewhere, but after 12 months working with R and quite a while looking at the docs, I still don't know (or have forgotten) how to replace all NA values in a matrix at once with some other value. I can do it column by column using is.na(), but I can't figure out how to do it for the whole matrix. My apologies, I am ashamed ;-) Michael

Please understand in the following that I am making relatively minor changes to legacy (non-TDD/BDD) code in Substruct and don''t have the time to refactor nicely right now. I''m just trying to get past the untested/un-speced cruft quickly to write the spec for my new code, so I''m looking for expediency over prettiness. I''m specifying before( :each ) do

Hi, Having just played with getting my first plain text story working, I like how it all fits together. It worked out nicely. However, I don''t feel our project needs to have stories as plain text, in fact it''s a slight hindrance for us. Is there any sensible mechanism for doing integration testing using rspec without plain text stories? Thanks, Rob

Hi, I am a beginner user of R. I have a trivial question ? I am almost ashamed I cannot figure it out does not matter how many times I am reading the help. I have a table in .txt format, tab delimited. I can read it with ?read.delim()? with no problems. Afterwards I would like to use boxplot function to see if there are any outliers in the column 5 of my data called TPAH16.ppm In the

Dear R-users, I am puzzled by for loops and am kind of ashamed to ask because it is so simple. There must be something I am missing in the way they are executed. Basically, I would like to iterate a given number of time and generate a bunch of stats (that's what loops are designed for, right?). Before doing this I simply want to test simple procedure and see if they work (ie got the syntax

I thought all you mongrelians might appreciate this: http://xkcd.com/327/ I haven''t laughed out loud at a comic in a while. I realize it''s a working group but I figure many here might get a laugh today out of this one. Steve

Hi all- I hope this is the right place for this. Anyway, the primary usage for the utility "FileCheck" is to pattern match for specific values in a stream. This is perfectly consistent and deterministic for the most part! However, when validating clang's LLVM-IR generation, it is possible to make an invalid match against the top few generated lines (the LLVM-IR Headers), which are

Ok, maybe I''m being particularly thick, but I''ve been trying to find the solution to this for a couple of hours now and I just can''t seem to be able to do it... I''m trying to write a step as such: Given("user $email is logged in") do |email| user = User.find_by_email(email) session[:user_id] = user.id end This is the way it would

Erm...no...the code is calling LLVMCreateMemoryBufferWithMemoryRange, not LLVMCreateMemoryBufferWithContentsOfFile... Or do you mean I need to load the module into memory before calling
