as.data.frame.spectra: Convert spectra to data.frame

In spectrolab: Class and Methods for Spectral Data

Convert spectra to data.frame

Description

Returns a data.frame that includes sample names, metadata (if present) and value data. One advantage over as.matrix, is that the metadata are returned.

Usage

  x,
  row.names = NULL,
  optional = FALSE,
  fix_names = "none",
  metadata = TRUE,
  ...
)

Arguments

row.names	does nothing. Here for compatibility with S3 generics

fix_names	Use make.names to normalize names? Pick one: "none" "row" "col" "both".
metadata	boolean. Include spectral metadata? Defaults to TRUE
...	extra parameters passed to the generic as_spectra

Value

data.frame with: sample_name, metadata (if any) and value.
