...ireframe=function(x,y,z,...){ panel.3dwire(x = x, y = y, z = z, ...) panel.3dscatter(x=df$Var1, y=df$Var2, z=df$Var2, ...) }) Which I coded according to what I saw here: http://www.nabble.com/add-points-to-wireframe-td12901155.html http://www.nabble.com/wireframe---add-data-points-td16984174.html However, this plots the wireframe, then puts the error message: Error using packet 1 'x' and 'units' must have length > 0 Any thoughts on what is incorrect here? Thanks.
