Dear all, I'm a lattice graphics newbie. I'm trying to make a cut through the 3D scatterplot with cloud(), so adding a partially transparent plate perpendicular to the z-axis in order to separate the cloud. code: library(lattice) cloud(Sepal.Width~Petal.Length*Petal.Width, data=iris) Could someone give me some hints on how to manipulate the panel functions in this case? Thanks! Jimmy -- View this message in context: http://n4.nabble.com/Lattice-cloud-help-tp955956p955956.html Sent from the R help mailing list archive at Nabble.com.
