Dear List, I'm trying to draw vector in XYZ with rgl under use of a cylinder3d. Therefore I scale and rotate a basis-cylinder). However, somehow the rotation is wrong as verified by overplotting arrow3d(). Where is my mistake? library(heplots) library(rgl) # ... 2 vectors data=data.frame(row.names=c('X','Y','Z'), x1=c(2,1,5),y=c(4,3,2))

Hi, I've been trying to follow the documentation that I am finding, but am running into trouble getting things set up correctly for postfix + virtual domains (using ldap) with dovecot LDA. I can get it to work without LDA, but I'm running into permissions problems when I try to run with LDA. I am wondering if anyone has any good examples of configuring this. I basically have a

Anyone out there using ActiveLDAP have an idea how I can accomplish creating an object one level below a known base where we have a variable item in the middle? That first sentence doesn''t even make sense to me. Here''s what I want to do: I have a user class that I use for managing users. Each user gets a ou called addressbook (which in turn will contain sub-entries, but

Dear Colleagues, I have x, y data (pollen and seed dispersal from oaks !) that I would like to fit with a function which look like this: p(a,b,x,y)=b/(2*pi*a?gamma(2/b))*exp(-(square_root(x?+y?)/a)power(b)) I am looking for a and b values that fit my data at best. Can someone give me hints to perform such an analysis with R ? Thanks a lot Sophie Sophie Gerber

Hi All, I want to select a level of a factor variable from a dataset. I have the folowing data: dataset: use factor: month (use$month, levels=February, July) > use[1:5,] month registration use department size 1 February KKG151GP Y Safety 1.6 To select February I tried: > use[use$month=="February"] Error in "[.data.frame"(use, use$month ==

This may be a more generic Ruby question, so I''m going to ask on the Ruby forum, but I''m trying to figure out if there is a way to pass in the string value of a variable as the name of a method. For example, I would like to do something like: def sort_obj_by_uid(objects,@attr) @tmparray = Array.new @tmphash = Hash.new for object in @objects if !

Hi, I am quickly losing the will to live over the lack of any kind of information at all about the SIEVE support that is listed in the dovecot features list. Does anyone have any information at all? I've grepped through the source, looked through all the configuration files, and googled a fair bit and come up with nothing at all. How would a user with maildir enable a sieve script?

Dear useRs, I'm trying to simply fill in the area under a curve using RGL. Here' the set up: x <- c(0.75,75.75,150.75,225.75,300.75,375.75,450.75,525.75,600.75,675.75, 0.5,50.5,100.5,150.5,200.5,250.5,300.5,350.5,400.5,450.5, 0.25,25.25,50.25,75.25,100.25,125.25,150.25,175.25,200.25,225.25) y <- c(0.05,4.91,9.78,14.64,19.51,24.38,29.24,34.11,38.97,43.84,

Hi I tried to customize help(), so it starts the compiled html help, and searches in all packages. I wrote the following function: > my.help function(topic){ help(topic, package=.packages(all=T), lib.loc=.lib.loc, chmhelp=T) } When I use it with >my.help(help) give the following error: Error in help(topic, package = .packages(all = T), lib.loc = .lib.loc, : No documentation

We've been running an Asterisk-based phone system here in our office for a year and a half, and it's pretty much been running smoothly. One employee who works out of the office has a problem that she can't make outgoing calls on a temporary basis every so often (a few times a day). No one else has this problem, her settings are fine, and she regains the capability spontaneously with no

Does anyone know how to assign values to LDAP objects with upper cased attributes? For example, you can normally do: user = User.new(@user) user.sn = params[:user][attr] But what about the case where there is an attribute that looks like OXTimeZone? You clearly can''t do: user = User.new(@user) user.OXTimeZone = params[:user][attr] I''m trying to

Hi! I am currently working on setting up an Asterisk system, and I was wondering if anyone has worked on an alternate mp3 player to mpg123. We have a library of MP3 files that we would like people to be able to select and play over the phone -- and this will require pause & resume, as well as fast forward / reverse (jump forward / jump back). It doesn't seem like mpg123 can do this. Is

Hello I have a rather simple code and for some reason it produces an error message. If someone can tell me why and how to fix it, I would be very greatful. Thank you in advance. ##### create data set.seed(10) n <- 200 # number of training points n.test <- 200 # number of test points p<-2 # dimension of input space z <-

I am trying to print out a list of strings of length 11 based on integers 0 through 10. The rules as given to me for the ordering are: The first digit must be 0. The 2nd digit must be 0 or 1. The 3rd digit must equal the 2nd digit or the 2nd digit +1. ... Given the final digit, n, all digits 0 through n must appear in a given sequence. So the final 1024 item list should look like 0 1 2 3 4 5

I wanted to move a file from one directory to another because my co- worker didn''t like where it was being put by puppet. I went into puppet and changed the name parameter of the the file directive. I then created a new file directive to delete the old file, but I was wondering if there was a better way to do this. So, just to clarify, I went from: file {"myfile": name

Dear expeRts, I am a new user of rgl, below is my first trial to plot a simple function in 3d. I managed to put the axes in the right locations, but: (1) The xlab, ylab, and zlab arguments are ignored; how can I put in axes labels? (2) Since I removed the axes in persp3d() the viewport is too small; is it possible to keep the size of the viewport? (3) The box is not correctly drawn, there

Dear r-helpers, Can one save a dynamic graphic produced by rgl, e.g.: open3d(); x <- sort(rnorm(1000)); y <- rnorm(1000); z <- rnorm(1000) + atan2(x,y); plot3d(x, y, z, col=rainbow(1000), size=2) as a dynamic figure that can be embedded in a pdf? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

Earlier today I sent a question to Frank Harrell as an R developer with whom I am most familiar. He suggested also that I put my questions to the list for additional responses. Next month I'll be giving a talk on R as an example of high quality open source software. I think there is much to learn from R as a high quality extensible product that (at least as far as I can tell) has never

Is it better to start Samba using in initd, or to use the script, much like the one provided by SuSE. ?? so far I have used the script, but I don't like the fact of having to start samba manually. I would much prefer to see it run as a service. just to confirm all it really involves is starting smbd and nmbd Rowan [TSS] Gerber Scientific Products http://www.gspinc.com

Hi, I would like to use xyplot to create a figure. Unfortunately, I cannot find documentation in xyplot to specify alternating the x-axis tick labels with the x-axis tick marks. I can do this with the regular R plot function as follows. #A small version of my data looks like this data<-data.frame(matrix(ncol=3,nrow=12)) data[,1]<-rep(c(1,2,3),c(4,4,4)) data[,2]<-rep(c(1,2,3,4),3)
