soil_color: Soil color by diffuse reflectance

In OxSR: Soil Iron Oxides via Diffuse Reflectance

Soil color by diffuse reflectance

Description

The function converts the visible soil spectrum to three-dimensional color systems, such as Munsell and RGB, using the CIE tristimulus values for the conversion. This allows for the standardized representation of colors and facilitates visual and comparative analysis.

Usage

soil_color(data = data,
           name_wave = "wave",
           tri_values = "std",
           plot = FALSE)

Arguments

data	A data.frame containing the wavelength and reflectance values.
name_wave	Character indicating the name of the column with the wavelength. It can be only the initial characters.
tri_values	Tristimulus Values. Values from the colorSpec package can be used.
plot	Logical, if TRUE, the plot with the colors is generated, the default is FALSE

Value

A data.frame with color values in Munsell, HVC, RGB, and ⁠hexadecimal code⁠.

Examples

# example code
data(soil_refle)

soil_color(soil_refle)

# tristimulus values {colorSpec}
soil_color(soil_refle, tri_values = "xyz1931.1nm", plot = TRUE)
