Description Usage Arguments Author(s) See Also Examples
Function to plot the Vertical Electric Sounding data. This function can create two different types of plots: resistivity and interpretation. The resistivity plot includes the apparent resistivity vs electrode spacing. In the interpretation plot, the values of the apparent resistivity vs electrode spacing and the thickness and real resisitivity of the layers are included.

Title of the plot |
type |
A character string specifying the plot type. Currently only ves (measurements and earth model), transformation (resistivity-depth transformation) and diagnostic are supported. |
trans.type |
A character string specifying the transformation type. Only direct, scaling, zohdy and zohdy.smoothed are currently supported. |
