geomaterials_bi_greater_than: retrieve the geomaterials whose birifrigence are higher than the given value.

Description

: Queries the list of geomaterials that minmum value of the given birifrigence value.

Usage

geomaterials_bi_greater_than(gt, ...)

Value

df, a data frame of geomaterials

Arguments

gt

float value.Birifrigence is calculated from refractive index as (rimax-rimin).Range: bi_min - bi_max.

...,

Further named parameters.Other optional arguments.

Details

This function releated to the field "bi_min" of geomaterials. retrieve all the geomaterials that has higher birifrigence than the given value(gt).

Examples

if (FALSE) {
df <-geomaterials_bi_greater_than(0.2)
}
