I am trying to understand the underlying structure of the dataframe that been used to plot the 3D surfaces in plotly
The following code is used to plot the 3D surfaces
library(plotly) plot_ly(z = volcano, type = "surface")
This gives the following output:
Here the z-axis value is 189, but when I try
it gives me 168. So I am trying to understand from where the 189 in the picture come from?
