Hi everyone! In a package I'm developing, I have created a custom function to get jackknife standard errors for the parameters of a gnm model (which is essentially the same as a glm model for this issue). I'd like to add support for bootstrap using package boot, but I couldn't find how to proceed. The problem is, my data is a table object. Thus, I don't have one individual per

I did some benchmarking of data frame code, and it appears that R 3.0.0 is far worse than earlier versions of R in terms of how many large objects it allocates space for, for data frame operations - creation, subscripting, subscript replacement. For a data frame with n rows, it makes either 2 or 4 extra copies of all of: 8n bytes (e.g. double precision) 24n bytes 32n bytes

I'm trying: R CMD Rdconv file.Rd --type=Ssgm If file.Rd contains \code{x} then this is currently translated as <s-expression>x</s-expression> I suggest instead translating to <code>x</code> (provided that R CMD Sd2Rd is changed to support the <code> tag; I just submitted that bug separately). Note that this is an enhancement, not a bug. This change would

Tim, I have reported some similar issues a while back and there was some discussion on this topic: http://tolstoy.newcastle.edu.au/R/devel/06/03/4609.html Good luck, Kevin On Tue, Jun 10, 2008 at 6:47 PM, Tim Hesterberg <timhesterberg at gmail.com> wrote: > Here are three different scenarios in which the browser() exits > when I don't want it to.

I would like to use the output from the map function in the package maps for use in, say, the spatstat package. I don't quite understand the coordinates for the border of the state: Example: library(maps) iowa<-map("region","iowa) x<-iowa$x y<-iowa$y There are NA's and duplicated coordinates. What would I need to do to use this in the spatstat owin command?

Hi, consider this one as an FYI, or a seed for further discussion. I am aware that many traps on sample() have been reported over the years. I know that these are also documents in help("sample"). Still I got bitten by this while writing sample(units, size=length(units)); where 'units' is an index (positive integer) vector. It works in all cases as expected (=I expect)

Insightful are pleased to announce we are now taking bookings for our latest course on "Bootstrap methods and permutation tests" in the UK on 23rd - 24th October. This course will focus in particular on two resampling methods, bootstrapping and permutation tests, which have been applied successfully to areas of statistical modelling where "traditional" standard errors,

Insightful is seeking a pre-doctoral student and an undergraduate student for two internship positions. The primary responsibilities are to assist in the development of software for high-dimensional regression and machine learning applications using least angle regression (LARS). The pre-doctoral candidate should have a background and interest in statistical methodology, algorithms, data

I suggest a simple enhancement to segments() and arrows() to facilitate drawing horizontal and vertical segments -- set default values for the second x and y arguments equal to the first set. This is handy, especially when the expressions for coordinates are long. Compare: Segments: < function (x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"), --- > function

Hola a todos, alguien que ya tenga en sus manos esos libros y/o otros más sobre todo sobre estadística descriptiva, inferencial, minería de datos y big data, o cualesquiera de R y que aunque haya pagado la ostia, no le importe compartirlo conmigo que no tengo la posibilidad de pagar por ellos, por favor, le estaría eternamente agradecido.

Fwiw, encoding magnitude in color is generally a bad idea. Using area(*not* radius) is also not great, but maybe it will work for you.

Hi, I read section 5, oop, of the R lang doc, and I am still not sure I understand how to build a class in R for oop. I thought that since I understand the oop syntex of Java and VB, I am wondering if the R programmig experts could help me out by comparing and contrasting the oop syntex in R with that of Java. For example, the basic class structure in Java is like this: public class Bicycle {

All I have been looking into the books on performing statistics in R, in particular I am interested in General Linear Mixed Models, for Randomized Complete Block Design Experiments The list I have come away with so far is: Mixed Effects Models in S and S-plus by Pinheiro (2002)

Hi I was wondering if there is a permutation test available in R for linear models with continuous dependent covariates. I want to do a test like the one shown here. bmi<-rnorm(100,25) x<-c(rep(0,75),rep(1,25)) y<-rnorm(100)+bmi^(1/2)+rnorm(100,2)*x+bmi*x H0<-lm(y~1+x+bmi) H1<-lm(y~1+x+bmi+x*bmi) anova(H0,H1) summary(lm(y~1+x+bmi)) But I want to use permutation testing to

Nick, First, thanks for responding. Secondly, I just want to create an exact copy of an already exisitng Value, this should be pretty simple to do but I'm unclear on how to do this? For example, PHINode::getIncomingValue (unsigned) returns a "Value" and I want to make a copy of that Value. Is there some other way to do this other than copyValue() that I'm missing? On Sat,
