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

Dear R-helpers! What it's means "Rank failure in Choleski decomposition" by using of function surf.gls {spatial}? Sincerely Yours Branimir K. Hackenberger

...ithub.com/libvirt/libvirt-go" GOPATH is set to /home/$USER/go I downloaded the package via go get; go get -v -u github.com/libvirt/libvirt-go. Please if somebody encountered this before, could you give me a hint if possible in order to solve this? Thank you very much in advance! Regards, Branimir

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?

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]]

...ted above but with the same results. Now, I am pretty sure that I am missing something simple here since this is a standard feature and should work out of the box if set correctly but so far I cannot see what I am missing. I would really appreciate any tip/help. Thank you very much!! Regards, Branimir

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 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(...) ..

I am using the wireframe function from lattice package. The problem that I have is very interesting. Namely, this is my code: x= seq(-pi, pi, len = 20) y=seq(-pi, pi, len = 20) xyz= expand.grid(x = x, y = y) xyz$z=sin(sqrt(xyz$x^2 +xyz$y^2)) trellis.par.set("axis.line",list(col="transparent")) trellis.par.set("panel", list(col="transparent"))
