Does anyone know if it is possible to display an R 3D array with ggobi or xgobi? For example, if I try ggobi(cubo) where cubo is an array with dimensions (100,100,22) I get "Error in as.data.frame.default(data) : can't coerce array into a data.frame" Should I transform the array into a dataframe with columns x,y,x,value ? Is there any other way? My goal is to visualize an slice, select a cell, and plot the values in the z axis for that cell.
