Could anybody explain this results? >sin(2*pi) -2.449213e-16 #should be zero >(10^16)*sin(log2(4)*pi) -2.449213 #should be zero too and explain what to do to correct this events? Thanks!!! Branimir K. Hackenberger

This is some interesting: > -8^(1/3) [1] -2 > x=(-8:8) > y=x^(1/3) > y [1] NaN NaN NaN NaN NaN NaN NaN NaN 0.000000 1.000000 [11] 1.259921 1.442250 1.587401 1.709976 1.817121 1.912931 2.000000 So, can anybody explain this?! (Why is x[1]^(1/3)=y[1]=NaN, but -8^(1/3)=-2?) Thx!!! [[alternative HTML version deleted]]

Dear all! I am using wireframe function from lattice package. Is it possible to remove box around the plot but to keep axis (x, y, z)? Thanks in advance! [[alternative HTML version deleted]]

After some investigation I found out that constrained ordination is working fine under R version 6.5.0 and 6.5.1 but not under any of newer versions. Is it posible to repair/make something in for example newest version of R 7.0 lito enble correct using of constrained ordination under BiodiversityRGUI environment?

Hi! When using multiple identities on one physical phone (Snom 320), I get check_auth: username mismatch, have <7705>, digest has <7736> messages when placing a call from a different account than the first one. From reading the asterisk source, I can see that the problem is that peer authentication is not matched against username, but against ip/port. I need to have multiple

Hi! I'm using asterisk 1.4.17 with twinkle and a custom phone based on iaxclient 2.0.2 and I'm struggling a bit with DTMF and features.conf. While the twinkle client is able to initiate an attended transfer using *2 (as configured in features.conf), the iax client is not. I can see the DTMF messages showing up on the asterisk console, but asterisk does not invoke the features

Hi all R-helpers!!! I have only one small question: Which visualisation method would you suggest for results of function cmeans {e1071}? Thanks! Branimir K. Hackenberger

I have been very satisfied with R-Excel interface (DCOM). Few months ago I have changed my OS to Linux-Mandrake, and now I am using OpenOffice.org Calc as spreadsheet. I would like to know does exist some R-OpenOffice.org interface or how is possible to use R-functions in OpenOffice.org Calc? Thanks a lot!

Hi! I'm trying to get t38modem working and started with the loopback mode. I installed everything according to http://www.voip-info.org/wiki/view/T38modem+configuration+with+Asterisk and used a stock asterisk 1.4.20.1 compiled from source. Openh323, ptlib_unix and t38modem are compiled from source as well, as outlined on the wiki. Hylafax starts sending the job (sudo faxstat -s shows one

Hi! I'm trying to build an HA system using heartbeat for failover. Everything works fine with SIP, but I cannot connect my IAX phone to the asterisk server using the managed IP address. Here is the configuration of the server (asterisk and the IP address are up, 'ip addr' and 'netstat' output): 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast

Hello everybody! First, allow me to wish you all a Happy New year! I have a problem with a small app that I wrote in Go and which uses libvirt go bindings. Actually, the problem exists only when I want to compile the code statically. Basically, when CGO_ENABLED=0 is exported, go (running go test, go run, go build) complains: undefined: libvirt.NewConnect When I try to compile the source

Dear colleagues, I am facing a problem that has been troubling me for last week and a half. Please if you are able to help or offer some guidance. I have a non-prod POC environment with 2 CentOS7 fully updated hypervisors and an NFS filer that serves as a VM image storage. The overall environment works exceptionally well. However, starting a few weeks ago I have been trying to implement virtlock

Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..

Hi ! Sorry for my ignorance. I have two questions: 1) which is in R the function to make a covariogram of spatial data ? 2) does anyone know if there exist the possibility in R of performing kriging with an arbitrary covariance function ? If I have well understood the Krig procedure offers only three possibilities (expcov, gauscov and sphercov) that are the common models for stationary and

Hi everybody, I've installed Free Fax For Asterisk in my Asterisk box but I don't understand how it works as when using SendFax application from dialplan, I can't find how to introduce destination fax number. How this application works? Do I have to call destination fax using Dial application, detect somehow that it's a fax and then use SendFAX application specifying FAXOPTs and

I use the ?covmod, but
