GeoRiskRRock: Shear strengths of rocks

In GeoRiskR: Data and functions for Geotechnical Risk Assessment

Description

Data sets covers the shear strengths from rocks

Arguments

cohesion	a numeric for the cohesion, in kPa
friction angle	a numeric for the inner friction angle, in degree
unit gravity	a numeric for the unit gravity, in kN/m^3

Details

The data set contains several columns : cohesion, friction angle, unit grivity, investigator, published year, rock name.

Value

Returns a matrix that contains above values for each rocks included in the data set.
