setSensorProperties: Set the "sensor.properties" attribute

In photobiology: Photobiological Calculations

Set the "sensor.properties" attribute

Description

Function to set by reference the "sensor.properties" attribute of an existing response_spct object.

Usage

setSensorProperties(x, sensor.properties = NULL, verbose = FALSE)

sensor_properties(x) <- value

Arguments

x	a response_spct object
sensor.properties, value	a list with fields named as described in Details.
verbose	logical Flag to enable warning when applied to object of unsupported class.

Details

Storing sensor properties in an attribute with a well defined format and minimum of information is intended to help with reproducibility. Unlike the filter.properties metadata, the sensor.properties metadata are currently not used in any computations. The attribute is intended to be used with photoelectric sensors, broadband and image, i.e., not for biological photoreceptors or photobiological responses.

model

character, identification code or name used by the supplier, required

type

character, "broadband", "spectral", "image" required

supplier

character, required

entrance.optics

character, "cosine", "dome", "sphere", "narrow" required

channels

data.frame, description of the channels, one channel per row, optional

signal.interface

character, "analog", "digital", and possibly others.

module.model

character, optional

module.supplier

character, optional

module.interface

character, optional

note

character, optional

Value

x

Note

This function alters x itself by reference and in addition returns x invisibly. If x is not a source_spct object, x is not modified.
