Hi all, I was wondering if there was a way to draw out grid lines in the cloud plots for lattice. I hunted all throughout the panel.cloud and panel. 3dscatter help pages and couldn't find anything to help me move forward with this. Do I have to get deeper into the drawing commands, or is there something more obvious I'm just not seeing? My goal would be to place grid lines on the bottom face of the box and make drop lines to the grid. #example dat set nirK.env.nmds$points = cbind(rnorm(30),rnorm(30),rnorm(30)) par.set <- list(axis.line = list(col = "transparent"),clip = list(panel = "off")) print(cloud(nirk.env.nmds$points[,3]~nirk.env.nmds$points[, 1]*nirk.env.nmds$points[,2], col="red",pch=16,cex=1.5,type=c("p","h"), strip = strip.custom(strip.names = TRUE), scales=list(arrows=FALSE,distance=2), xlab="NMS 1", ylab="NMS 2", zlab="NMS 3"), par.settings=par.set, split = c(1,1,2,1), more=TRUE) Many thanks!!
