retrieve the geomaterials whose refractive index is within an given range(gt,lt).

: Queries the list of geomaterials that have refractive index within an given range(gt,lt).

Usage

geomaterials_ri_range(gt,lt, ...)

Arguments

gt

float value. Refractive index, from (rimax>=).

lt

float value. Refractive index, to (rimin<=)

...,

Further named parameters.Other optional arguments.

Value

df, a data frame of geomaterials

Details

This function releated to the fields "ri_min" and "ri_max" of geomaterials. retrieve all the geomaterials that has the refractive index within the range of (gt,lt).

Examples

if (FALSE) {
df <-geomaterials_ri_range(0.2,0.5)
