Create a new measure tibble

Constructor for creating a single measurement object containing location (e.g., wavelength, retention time) and value pairs.

Usage

new_measure_tbl(location = double(), value = double())

Arguments

location

Numeric vector of measurement locations (e.g., wavelengths, wavenumbers, retention times).

value

Numeric vector of measurement values (e.g., absorbance, intensity, signal).

Value

A tibble with class measure_tbl containing location and value columns.

See also

new_measure_list() for creating collections of measurements, is_measure_tbl() for checking object class.

Examples

# Create a simple spectrum
spec <- new_measure_tbl(
  location = seq(1000, 1100, by = 10),
  value = sin(seq(1000, 1100, by = 10) / 50)
)
