trimInstrDesc {photobiology}

Trim the "instr.desc" attribute

Description

Function to trim the "instr.desc" attribute of an existing generic_spct object, discarding all fields except for 'spectrometer.name', 'spectrometer.sn', 'bench.grating', 'bench.slit', and calibration name.

Usage

trimInstrDesc(
  x,
  fields = c("time", "spectrometer.name", "spectrometer.sn", "bench.grating",
    "bench.slit", "entrance.optics")
)

Arguments

x

a generic_spct object

fields

a character vector with the names of the fields to keep, or if first member is '"-"', the names of fields to delete; "*" as first member of the vector makes the function a no-op, leaving the spectrum object unaltered.

Value

x

Note

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