Hello! I have a question on uniform distribution. I want to plot n, say 20, points, uniformly distributed, in a circle, with radius=0.1 and center,say, (0.4, 0.8) I do not know how~ Thank you for your time. Yours Wolfgang Amadeus [[alternative HTML version deleted]]

How precise is R numerically? For example I wrote the following function for calculating the volume of the ball inscribed in the unit cube in m dimensions. In order to see what happens in 40 dimensions, I created an output of 24 digits. But how many are precise? Thanks Josef Eschgf?ller Ferrara --------------------------------------- Vol = function (m) {if (m<=1) 1 else Vol(m-2)*pi/(m+m)}

Dear Helper: Thank you very much for your time on this question. It is a little long and complicated. Generate a clustered pattern in [0; 1]2 as follows: (a) Generate n, say 20, independent cluster centers (which can be called parents) that are distributed i.i.d. uniformly in the unit square; (b) then m,say 100, daughters are assigned i.i.d. uniformly to these parents and such that each

Hello While searching the archives and googling for : -login script to map drives according to group membership I saw lots of complicated solutions (on-the-fly scripts, group directories) etc. but the following works very well for me: I downloade dthe ifmember.exe from the microsoft website, and stuck it in the netlogon directory (not the scripts directory)

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) +

Estimada Lista, Deseo aplicar una función a cada fila de un data frame con un argumento opcional. En la función orginal, el argumento opcional debería poder ser escalar o vector. Necesito definir una función 'aplicaratodasfilas' que llama a otra función 'atomica' que no admite vectores y que requiere también argumentos opcionales. Pongo un ejemplo: # Se aplica a cada fila.

I am trying to "dial" a GTalk, ie @gmail.com, address. I inscribed this address in jabber.conf on the buddy= line. Upon executing the Dial application, I hear only a brief brief ring, then nothing. What might be the trouble? As the Dial application starts trying, the JABBER chatter on the console includes some "INCOMING" entries that name IP addresses. The one with

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

Can someone explain to me what is happening here: ~ $ touch foo ~ $ ln foo bar ~ $ ls foo bar bar foo ~ $ mv foo bar ~ $ ls foo bar bar foo I try to move a file over a hard linked copy of itself and the move fails, but there is no error. Is this the intended behavior? -- Ben Escoto

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

Hi, Apart from the Calysto project ( http://www.cs.ubc.ca/~babic/index_calysto.htm), is there any other static code analysis tool based of the LLVM framework ? Calysto may be great but it seems that the source is not available (yet?). I was quite excited by Oink/Elsa few years ago but the project is almost dead even if the C++ parser is far from being complete. It seems to me that everything is

Dear all, the dataset documented under ?crimtab was also used in: @article{TreloarAE1934, title = {The adequacy of "{S}tudent's" criterion of deviations in small sample means}, author = {Treloar, A.E. and Wilder, M.A.}, journal = {The Annals of Mathematical Statistics}, volume = {5}, pages = {324-341}, year = {1934} } The following is

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

I'm running into some hard-to-understand behavior with the evaluation environment when NextMethod is used. I'm using square-bracket indexing into objects, and the evaluation environment of the expression inside the square brackets seems to change depending on what kind of comparison operators are used. This behavior happens when the following conditions are met (this is what I've

Sorry to all bothering you with a trivial question: I am using R (rw0630 for Win32) and am simply unable to read-in the *.txt data. I've tried to copy the file (prum.txt) to different directories of rw0630 but get uniformly the answer "object "prum.txt" not found". Which is the default directory for read.table() ?? Thanks! Z.

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 all, I can't get stereo with wineasio, even the new verison of wineasio which I have compiled > 1.7.4. when I open an app with wine, I do see the connections in Qjack connections, but It is not in stereo Ardour can verify this, and both left and right connection are connected from wine to jack, I have googled for this answer to no aval and I have asked numerious times on IRC in

For some files, file.copy() doesn't copy these files correctly. Here you will find a file (Bitmap, 769Kb) to reproduce the problem: http://www.statistik.uni-dortmund.de/leute/ligges/R/test1.bmp Using file.copy("c:/test1.bmp", "c:/test2.bmp", overwrite = TRUE) produces a second file with the size of ~1.4 Mb: http://www.statistik.uni-dortmund.de/leute/ligges/R/test2.bmp
