Import Metadata

Reads metadata associated with an ANKOM RF experiment.

Usage

read_metadata(file, sheet = "metadata")

Arguments

file

Path to a metadata file.

sheet

Sheet name containing metadata.

Value

A data frame containing experimental metadata.

Details

Metadata are used to identify bottles, treatments, replicates, and other experimental information required for downstream analyses.

This function is typically used together with:

• read_ankom()

• process_ankom()

as part of the standard ANKOM workflow.
