similar to: scatterplot3d: fractionary xrange

Dear all, sorry if it's obvious but I wasn't able to find a solution by myself. I have a text file filled with 3 colums representing xyz coodinates (i.e. positions) of an objects. Can I have in R a 3d plot representig my object' s positions? I guess that I can but I don't know how. Any help is much appreciated Thanks a lot -a- Andrea Valle DAMS - Facolt?? di Scienze

Hi to all, I usually use R for simple 2D graphs so now I cannot solve the following problem (which I suppose very simple too). I'm using scatterplot3d. I want to add dotted lines parallel to the 3 axes, in order to create a sort of cage in the 3D box (so to represent subdomains in my dataspace). I saw that points3d can be used to draw points or lines to the existing plot but actually

Hi, I'm trying to write a small microsimulation in R: that is, I have a dataframe with info on N individuals for the base-year and I have to grow it dynamically for T periods: df = data.frame( id = 1:N, x =.... ) The most straightforward way to solve the problem that came to my mind is to create for every period a new dataframe: for(t in 1:T){ for(i in 1:N){ row = data.frame( id =

Dear Sir/Madam, I got some problem about using R. I am a student, and need to use R a lot.

I installed samba 3.0015. I have a problem when I try to browse my machine from a windows client. In effect I am not able to "open" my unix-client. I checked nmbd and smbd and they are running. If I try from my unix-clinet: smbclient -L my_user -W my_domain -L my_PDC I can see shares. If I try from my unix client: smbclient -L my_user -W my_domain -L my_unix_client I get session setup

Hi, I'd like to build a personal PBX connecting 4 or 5 analogic phones with a ADSL line and I'd like to know what is the right card I need I visited digium site and I think TDM400 could be the right choice but I cannot understand how it works...I think it has 4 slots where 4 modules (FXS or FXO) can be inserted. How many cards do I need to connect my ADSL line to 5 phones? I think I

Hello, I have a strange problem affecting samba-3.0.10-1.4E.12.2 on a Red Hat Enterprise Linux AS release 4 system. We have a multi-domain configuration here at University of Verona (Italy). We use Samba as PDC for several faculties. Each faculty has its own daemon instance and its own smb config file: [root@ldapvr1 ~]# ls /etc/samba/smb.* /etc/samba/smb.conf

Hi all- terribly beginner question here, but I can't figure out how to put dates as the values for my x range in a plot. Example: xrange <- results$current yrange <- results$DIFF plot(xrange, yrange, type="n", xlab="Date", ylab="Differential") lines(results$DIFF, type="l", lwd=1.5, col="red") Where xrange is: > xrange [1]

Dear R-users, I'm working with the Rpart package and trying to understand how the procedure select the best split in the case the method "class" and the splitting index "Gini" are used. In particular I'd like to have look to the source code that works out the best split for un unordered predictor. Does anyone can suggest me which functions in the sources I should
