Hi, I use samba for one year only, but with full satisfaction. Only with latest cvs tree I discovered some (maybe particular) problem. In mixed environment of win95oemII and NT4 workst (sp3 or sp4) we share some Paradox 7.0 database on linux server (Rh5.2 and 2.2.0-pre1 kernel). Paradox controls multiuser access to the data with three files: PDOXUSRS.NET (user names etc?), and two lock files,

Last week I asked about data ellipses with rgl:::ellipse3d() with lines showing the principal axes. (The goal is a visual demonstration of PCA as a rotation of variable space to component space.) I was trying, unsuccessfully, to use princomp() to generate the PCA axes and plot them using segments3d: > > PC <- princomp(trees) > > sdev <- PC$sdev # component standard

Hi I'm trying to make a 3d plot showing a point cloud, the corresponding data ellipse and the principal axes of the ellipse as vectors. library(rgl) data(trees) cov <- cov(trees) mu <- mean(trees) plot3d(trees, type="s", size=0.5, col="blue", cex=2) In this step, an extra box is added. I've tried using box=FALSE, but it has no effect. # how to avoid the

Hi all Maybe someone knows a way to solve this anomaly in sample(): I like to compute a sample (n=100) with replications from a population of 2500 units but if I draw repeated samples from it I dont get what seems to be a representative sample if I look at other partitions of the population. Enclosed is the population g99 with 4 columns: (units, partition 1 (site), partition 2 (type), weights);

I have a general style question about R coding. Suppose I'm writing a function (foo1) that calls other functions (foo2, foo3, ...) which have complicated argument lists (e.g. optim(), plot()), _and_ I may be calling several different functions in the body of foo1. Since foo2 and foo3 have different sets of arguments, I can't just use "..." ; I did write some code a while ago

Hi, Here is the function DrawDensity3D in package VecStatGraphs3D. My question is: if we use more layers than one, could we change the function in a way that in the final plot only the outmost layer is drawn (the inner layers omitted)? Best regards, Atte Tenkanen function (vectors, Div = 40, Layers = 3, DrawAxes = FALSE) { open3d(windowRect = c(100, 100, 800, 800))

Brian, I just tried your version rgl_0.70-2 with R-2.5.0 on FreeBSD 7.0-CURRENT (i386) and it works! Thank you very much for this competently and very fast help. Next I will try if it compiles on amd64, too ...

I can't create new folder in a czech Win95 explorer on a unix using samba 1.9.18p7. The problem is that Windows exporer uses for the creation new folder a name containing characters above 128. The explorer creates new folder in a two phases: the first It creates directory named Nov<A0> slo<A7>zka and next it gives to user posibility to change this name. Crazy !!? The first phase

Dear all, It is not a R related problem rather than statistical/mathematical. However I am posting this query hoping that anyone can help me on this matter. My problem is to get the Geometrical Interpretation of Eigen value and Eigen vector of any square matrix. Can anyone give me a light on it? Thanks and regards, Arun [[alternative HTML version deleted]]

Dear list, I'm trying to visualise some ellipsoidal shapes in 3D. Their position, axes, and angular orientation can be arbitrary. I saw an ellipse3d function in rgl; however it is heavily oriented towards the statistical concept of ellipse of confidence, whilst I am just concerned with the geometrical object. Below is my current implementation. It is quite slow when creating many shapes, so

I have a character vector j1 created from dimnames and want it to convert it to numeric. Like the first element: > j1[1] f896 1 896 > as.numeric(j1[1]) [1] 1990 why is it not 896 as it should be? This is true fr the whole vector. Thanks W.P. [[alternative HTML version deleted]]

Dear list, I have to plot some geometrical shape given as list of points. My need is the following: let's say my shape is a 1 inch large square; how can I plot it with R in a graphic format that gives me an image *exactly* 1 inch large? I tried to set oma, mar and fin parameters, but with no success. I'm currently using the xfig driver for the final images are to be included in latex

before getting scolded for submitting a (non-)bug report: when using the 'symbols' function for plotting boxplot data (i.e. using 'boxplots' symbols), I noted that the x/y-position of the symbols is associated with the center of the box. while this is obviously natural for a usual plotting symbol (say a circle or a rectangle), it is probably never desired if one uses the

Dear R helpers, this is a question connex to the subject of reading large data-sets - I have a large db (MySQL) ~80'000 records for each year / 120 variates from which I extract relevant info to be treated in R (no problem) Now each record in my db represents an experimental unit; moreover I will get - in a few days- a set of separate files(one for each records....~80'000 files pro

Dears, I've been learning biplot (Gabriel, 1971) and I found the function 'biplot', inside of the package 'stats', useful but, a bit limited. So, I'm thinking to start a colaborative package to enhance this methods to other multivariate methods. In this way, I would like to start it, making public a new function (biplot.pca, still in development, but running) that make

Dear all, I've been learning biplot (Gabriel, 1971) and some days ago I sent for this list a procedural function with invitation for a collaborative package. Jari Oksanen made some suggestions and I agree with all. So, I reworked the function under the object-oriented programming (OOP/S3). I think it is now a good frame for more resources. Below it is the function and a small script to
