geomaterials_dens_greater_than: retrieve the geomaterials whose density are higher than a given value.
Description
: Queries the list of geomaterials that have higher density than gt.
Usage
geomaterials_dens_greater_than(gt, ...)
Value
df, a data frame of geomaterials
Arguments
gt
float value.
dmeas: measured density of the mineral.
This is either the lower limit (if there is a dmeas2) or average (if there is no dmeas2).
dmeas2:measured maximum density of mineral
...,
Further named parameters.Other optional arguments.
Details
This function releated to the field "density_min" of geomaterials.
retrieve all the geomaterials that has higher density than the given density(gt).
