Description

Data sets covers the ratio of sand-silt-clay from soils

Arguments

sand

a numeric for the ratio of sand

silt

a numeric for the ratio of silt

clay

a numeric for the ratio of clay

Details

The data set contains several columns : sand, silt, clay, optimum water content, dry density, liquid limit, plastic limit, shrinkage limit, USCS classification, investigator, published year, soil name.

Value

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