weird error: Coercing LHS to a list
Hi all! I'm trying to build a simple class, but I'm getting a weird error. E.g. if I do: ========== gregion = setClass("gregion", contains = "data.frame", representation(name = "character", poly.x = "numeric", poly.y = "numeric" )) gregion$name = "North America" ========== Then I get this message: Warning message: In

Experimental data analysis (eda) function
Hello, I cant seen to find the equivalent function in version 2.1.1. This always served as a nice preliminary tool for looking visually at data.

extract all numbers from a string
Hi all, I have been beating my head against this problem for a bit, but I can't figure it out. I have a series of strings of variable length, and each will have one or more numbers, of varying format. E.g., I might have: tmpstr = "The first number is: 32. Another one is: 32.1. Here's a number in scientific format, 0.3523e10, and another, 0.3523e-10, and a negative,

locfit and memory allocation
Hello I am getting memory allocation errors when running a function that uses locfit within a for loop. After 25 or so loops, it gives this error. "Error: cannot allocate vector of size 281250 Kb" Running on linux cluster with a Gb of RAM. Problem never happens on my OS X (less memory). The total data is 130 cols by 5000 rows The first 129 cols are response variables, the 130th

R-beta: is there a way to get rid of loop?
Here is a programming question. The code I am using is quite slow and I was wondering if there is a way to get rid of the for loop. I am dealing with "interaction" in 2x2 table, and am using Edwards's G_I (Likelihood, p. 194). I label the cells in the table as follows stim response "y" "n" total -------------------------------- y hit miss nsignal

I know there is a hash_including, which is quite useful. Are there by chance any matchers for ensuring a hash includes only the specified values, or that it doesn''t have certain values? Thanks, Steve

spec_server doesn''t update ''required'' files
I have some specs that ''require'' other files. When running spec_server, if these required files are changed, it''s not picked up when the specs are run. I have to restart spec_server to get the changes recognized. Is there an option or some such to have spec_server reload required files as well when a spec is run? Thanks, Steve

Getting PG Manager Lite by EMS running.
I just installed on my up to date FreeBSD 5.4 box. I'm a little confused as to whether or not there are things I need to configure or not. I went to go through the docs, and it was talking about using a file named "config" as a template, and modifying from there. Well that file didn't exist anywhere on my machine, or in the source I downloaded. In fact, looking in the Wine CVS

naive variance in GEE
Hi, The standard error from logistic regression is slightly different from the naive SE from GEE under independence working correlation structure. Shouldn't they be identical? Anyone has insight about this? Thanks, Qiong a<-rbinom(1000,1) b<-rbinom(1000,2,0.1) c<-rbinom(1000,10,0.5) summary(gee(a~b, id=c,family="binomial",corstr="independence"))$coef

"rbinom" not using probability of success right
I am trying to simulate a series of ones and zeros (1 or 0) and I am using "rbinom" but realizing that the number of successes expected is not accurate. Any advice out there. This is the example: N<-500 status<-rbinom(N, 1, prob = 0.15) count<-sum(status) 15 percent of 500 should be 75 but what I obtain from the "count" variable is 77 that gives the probability of

Stories location
Should the stories dir be located on the project root? I was expecting to find it located under spec/ but there isn''t anything there, just the stories dir off of /. Also there don''t appear to be any rake tasks for stories, nor generators. Should there be any? Thanks, Steve

A problem about outer()
Dear all, I have something about function outer() that I can't understand. Just see the following example. The two NaNs are due to 0/0, but I can't figure out the cause of the last two errors. I wonder if some one can explain this for me. ___________________________________________________________________ > sx=rbinom(10,1,0.5);ot=rbinom(10,1,0.5);ag <- rbinom(10,100,0.3);ho

mgcv bam() with grouped binomial data
Hello, I'm trying to use the bam() function in the R mgcv package for a large set of grouped binary data. However, I have found that this function does not take data in the format of cbind(numerator, denominator) on the left hand side of the formula. As an example, consider the following dat1 <- data.frame(id=rep(1:6, each=3), num=rbinom(18, size=10, prob=0.8), den=rbinom(18, size=5,

nls and rbinom function: step factor 0.000488281 reduced below 'minFactor' of 0.000976562
I  am trying to learn nls using a simple simulation. I assumed that the binomial prob varies linearly as 0.2 + 0.3*x in  x {0,1}, and the objective is to recover the known parameters a=0.2, b=0.3 frame d has 1000 rows... d$x<-runif(0,1)               d$y<-rbinom(1000,1,0.2+0.3*d$x)  table(d$y,cut(d$x,breaks=5));   (-0.000585,0.199] (0.199,0.399] (0.399,0.599] (0.599,0.799]

problem with "transform" and "get" functions
Hello, I'm having a problem using the "transform" and "get" functions. I'm probably making a dumb mistake, and I need help! I start by making a small simulated dataset. I save the names of the variables in "var.names." Without getting into the details of it, I have to create a custom function to perform some statistics. As part of this, I need to sequentially

How does the r-distribution function work
I am trying to understand what rbinom function does. Here is some sample code. Are both the invocations of bfunc effectively doing the same or I am missing the point? Thanks, Pieter bfunc <- function(n1,p1,sims) { c<-rbinom(sims,n1,p1) c } a=c() b=c() p1=.5 for (i in 1:10000){ a[i]=bfunc(30,p1,1) } b=bfunc(30,p1,10000)

sample(c(0, 1)...) vs. rbinom
Greetings.? My wife is teaching an introductory stat class at UC Davis.? The class emphasizes the use of simulations, rather than mathematics, to get insight into statistics, and R is the mandated tool.?? A student in the class recently inquired about different approaches to sampling from a binomial distribution.? I've appended some code that exhibits the idea, the gist of which is that using

rspec causing validates_presence_of to validate twice?
I had posted this on the regular Rails list, but upon trying this in script/console, it seems like the behavior only exists when running rspec. I''m getting some weird behavior in one of my models. I have a model defined something like this class User < ActiveRecord::Base attr_accessor :password validates_presence_of :password end If I validate the model without specifying a
