Hi I am having a bit of difficulty with changing the canvas size on a trellis/lattice plot. I am plotting two "cubes" of 3-dimensional random numbers, as follows: library(gsl) library(lattice) q <- qrng_alloc(type="sobol", 3) npoints <- 200 rs <- qrng_get(q,npoints) # Plot the normal variates in a 3-dim cube p1 <- cloud(rnorm(npoints) ~ rnorm(npoints) +

Well, I'll start by saying my particular optimisation use case looks like it's not

Hi, I'm interested in performing a regression of dependent variable y on independent variable x, where (x,y) are known only for y < c, where c is a constant. For y >= c, neither x or y are known. This is called a truncated regression, I believe. I read a post on the R help list, that recommended doing the following: "The form for the response is Surv(c,y,1), but it

The survexp function can fail when called from another function. The "why" of this has me baffled, however. Here is a simple test case, using a very stripped down version of survexp: survexp.test <- function(formula, data, weights, subset, na.action, rmap, times, cohort=TRUE, conditional=FALSE, ratetable=survexp.us, scale=1, npoints, se.fit,

Hello ! I have a quick question about loops. For example, I have a 1 * 1 square and its inscribed circle tangent i, whose radius, of course, is also 1. The loop here is as the following: generate n points, say 5, in the square randomly repeatedly until we have five in total in the circle, then we stop, otherwise we continue. I do not know how ! Help me Please ~ Thank you very much for

Dear All, I am struggling with the following problem: I am given a NxN symmetric matrix P ( P[i,i]=0, i=1...N and P[i,j]>0 for i!=j) which stands for the relative distances of N points. I would like use it to get the coordinates of the N points in a 2D plane. Of course, the solution is not unique (given one solution, I can translate or rotate all the points by the same amount and generate

Hello, I've written a short code (below) to write 3D unstructured grid to binary VTK files from R. Problem : I can only write integers with the command : data<-as.numeric(c(3.3)) storage.mode(data)<-'integer' writeBin(data,bfile_celldata,endian="swap") the function storage.mode(data)<-'long' looks fine, but the VTK file is not readable. thanks for any

How about: > vec_npoints (x) > vec_nrecords (x) > vec_nobs (x) Depending on whether you want to promote geometry, databases

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Hello list, I wrote a simple program to plot data on polar axes, taking advantage of the plotrix package and its function radial.plot. The basic plot works fine, but I am having difficulties with the formatting. There are three problems, but I thought I would attack them one at a time. Here is the first: If my data set contains values with all vector lengths between 0 and 100 (and various

Hello all: Is there any way to add points to a point pattern, while keeping a given minimum distance amongst this new points and the pre-existing points? Thanks, Frederico [[alternative HTML version deleted]]

Hello, I'm trying to get a few turnpoints for a financial time series. There is a function in pastecs that does that. However, I get a large number of turnpoints: library(pastecs) data(EuStockMarkets) dax <-EuStockMarkets[,1] plot(dax) turnp <-turnpoints(dax) summary(turnp) #gives 925 peaks/pits!!! How can specify to get only 30 turnpoints? Second question: the extract function

Hi, I've been looking at improving atomicrmw & cmpxchg code more, particularly on architectures using the load-linked/store-conditional model. The summary is that current expansion for cmpxchg seems to happen too late for LLVM to make meaningful use of the opportunities it provides. I'd like to move it earlier and express it in terms of a first-class pair of "load linked"

Hola, estoy usando knitr en un documento latex, pero me gustaría aumentar el tamaño de la fuente del "output" (creo que por defecto usa "normalsize"). Alguien puede decirme como cambiar esta opción. Muchas gracias. Manuel [[alternative HTML version deleted]]

Hola a tod en s: Tengo una función del tipo f &lt;- function(...) { args &lt;- list(...) # validaciones } En la cual debo realizar una validación diferente para cada argumento que se pase, y no consigo identificar los nombres de los argumentos con names(args). ¿Alguna idea o sugerencia acerca de cómo realizar este tipo de validaciones?. Gracias. Salud! Eva
