Here is a first draft : http://addictedtor.free.fr/misc/wiki.png I would like to put some code on the left, but i'm not inspired which code, something simple, involving iris maybe, i don't know. Maybe something with a puzzle or a planet, or both (echoing the symbol of wikipedia) ... Any ideas Romain. -- I started that hacking demo(bivar) from rgl : require(MASS); # parameters: n<-50; ngrid<-40 # generate samples: set.seed(31415) x<-rnorm(n); y<-rnorm(n) # estimate non-parameteric density surface via kernel smoothing denobj<-kde2d(x, y, n=ngrid) den.z <-denobj$z # generate parametric density surface of a bivariate normal distribution xgrid <- denobj$x ygrid <- denobj$y bi.z <- dnorm(xgrid)%*%t(dnorm(ygrid)) # visualize: zscale<-20 # clear scene: clear3d() clear3d(type="bbox") clear3d(type="lights") # setup env: bg3d(color="white") light3d() # Draws parametric density surface3d(xgrid,ygrid,bi.z*zscale,color="yellow",front="lines", back="cull") # the file is from here : http://developer.r-project.org/Logo/ rgl.bg(sphere=TRUE, texture="/home/romain/Rlogo-4.png", back="filled" ) -- visit the R Graph Gallery : http://addictedtor.free.fr/graphiques mixmod 1.7 is released : http://www-math.univ-fcomte.fr/mixmod/index.php +---------------------------------------------------------------+ | Romain FRANCOIS - http://francoisromain.free.fr | | Doctorant INRIA Futurs / EDF | +---------------------------------------------------------------+ _______________________________________________ R-sig-wiki mailing list [EMAIL PROTECTED] https://stat.ethz.ch/mailman/listinfo/r-sig-wiki
