Hi R-helpers Has anyone had any experience doing CGI or Servlets or using an httpd server in R? Context: we are interested in running dynamic demographic calculations on the internet (life tables, and such) in response to form submissions. I might do simple cgi to get started, but loading in data each time seems like it would be quite, quite slow. I have looked at Rserv, but I am most

Hi all, I was wondering if I might subscribe this list to gmane.org, so I (and everyone else) might view and search in with a newsreader? Also--is there any way to get it indexed by google, maybe along with the r-help list (or is it already but I haven't found it)? Thanks for your consideration W

Hi R-heplers, I would like to print various matrices, dataframes, tables, etc to files, preferably nicely formatted postscript for import into papers. Is there a way to do this? I know ?cat, ?writeLines, ?format, ?paste. But I am not sure of a good combination of these in order to get a nice looking table of information. Any ideas? I guess I want (almost) publication ready output, just

Hi All, (I have a degree in math, but I am too embarassed to ask my colleagues, so here goes:) I would like to get a vector normal (orthogonal) to a plane formed by two other vectors. In matlab I do this: v1 = [.4, .6, .8]; v2 = [.9, .7, .2]; nn = cross(v1,v2) (gives ~[-.48, .65, -.24] if I do R> cross(v1, v2), I get .94. Huh? Thanks for all your help, again. W

Dear R experts, I would greatly appreciate your help with R's hypertext online documentation, which I can pass on to our system manager. We are running version 1.7 on sparc-sun-solaris2.9 using netscape7 browser for displaying the help. The system is working, but there are a few frustrating details that I hope might be fixed. Here are three problems we are having: 1. When the R session

Hi ,all : I am a newbie to here and I also install the 389 ds in our company for managering all users account and passwd . Today , The boss asked me if the ds could set the users vnc screen geometry in the config file . Because the user's computer screen is not the same and have different geometries. If it could , then we were happy that can solve the user's vnc problem . Then , I

Hi, regarding to this problem I made some progress. After going back to Jessie, and samba 4.2.14 the following configuration works.

Hi R-helpers, I have a data.frame with three columns (lots more reps though in each), like so: 'FOO' 'BAR' 'RESULT' 1 .01 75 1 .05 12 1.1 .01 100 1.1 .05 50 1.2 .01 75 1.2 .05 12 I am calling boxplot(RESULT ~ FOO:BAR, ...) This

Hi all, I dump the result of a long simulation, which I know has run to completion and returned a fairly complex list of lists of things. However, when I try to read it back in, I get the following error: > source ('../SIMULATIONS/run.1.R') Error in structure(list(do.extinction.runs, alpha = 1.8, delta.change = 0.005, : Object "do.extinction.runs" not found I think the

Hi R-developers I have noticed a strange little bug/feature: I often create pdf's of plots, then edit them in Adobe Illustrator. Generally this works great, but whenever I have text that is aligned vertically (along the y-axis usually), the text is written out as lots of individual objects. When the text is horizontal (x-axis, other stuff), it is all one object. I would prefer one object

I'm quite new to Asterisk and using Asterisk 13 on FreeBSD current. Asterisk is behind a NAT router, the physical setup is very much a trivial one. The Asterisk PBX is supposed to act as the telephone gateway for several VoIP/SIP phones. I'm using throughout pjsip as configuration, I have no experience with chan_sip since I started recently using Asterisk for several SoHo and lab's

Hi R-helpers I would like to plot some planes which are perpendicular to the x-y plane, such as x=y. Is there a way to do this in wireframe? I realize that I am not plotting a function of x, y since there are infinite number of z's that satisfy the above relation.... Hmm... Somewhat related, I would also like to plot a line in 3 d space... Finally, if you are feeling really brave, I

Hi all, Is there any documentation on running R like one would run a shell or Perl script, with out/input directed appropriately, environment variable access, and command switch processing? I looked some, and even remembered to check the FAQ, but couldn't find anything. Thanks W

Hi, Given a positive integer N, and a real number \lambda such that 0 < \lambda < 1, I would like to generate an N by N stochastic matrix (a matrix with all the rows summing to 1), such that it has the second largest eigenvalue equal to \lambda (Note: the dominant eigenvalue of a stochastic matrix is 1). I don't care what the other eigenvalues are. The second eigenvalue is

Hello, I have a short question about the prcomp function. First I cite the associated help page (help(prcomp)): "Value: ... SDEV the standard deviations of the principal components (i.e., the square roots of the eigenvalues of the covariance/correlation matrix, though the calculation is actually done with the singular values of the data matrix). ROTATION the matrix of variable loadings

I have been looking at the "eigen" function and have reintroduced the ability to compute (right) eigenvalues and vectors for non-symmetric matrices. I've also made "eigen" complex capable. The code is based on the eispack entry points RS, RG, CH, CG (which is what S appears to use too). The problem with both the S and R implementations is that they consume huge amounts

Hi, I am new to R and have a couple of questions. I know how to list all objects (with ls()), but how to list all properties of them? For instance, I found function object.size(), but I would also like to know whether one object is a dataset or just one vector (variable) or even only one value, etc... And another question - how to save workspace to a custom location while running R? Is there

Dear all I am so glad the R can provide the efficient calculate about eigenvector and eigenvalue. However, i have some puzzle about the procedure of eigen. Fristly, what kind of procedue does the R utilize such that the eigen are obtained? For example, A=matrix(c(1,2,4,3),2,2) we can define the eigenvalue lamda, such as det | 1-lamda 4 | =0 | 2 3-lamda | then

Dear all, I am currently working on the calculation of eigenvalues (and -vectors) of large matrices. Since these are mostly sparse matrices and I remember some specific functionalities in MATLAB for sparse matrices, I started a research how to optimize the calculation of eigenvalues of a sparse matrix. The function eigen itself works with the LAPACK library which has no special handling for
