make_rel: Make spectral intensities relative

In OpenSpecy: Analyze, Process, Identify, and Share Raman and (FT)IR Spectra

Make spectral intensities relative

Description

make_rel() converts intensities x into relative values between 0 and 1 using the standard normalization equation. If na.rm is TRUE, missing values are removed before the computation proceeds.

Usage

make_rel(x, ...)

## Default S3 method:
make_rel(x, na.rm = FALSE, ...)

## S3 method for class 'OpenSpecy'
make_rel(x, na.rm = FALSE, ...)

Arguments

x	a numeric vector or an R OpenSpecy object
na.rm	logical. Should missing values be removed?
...	further arguments passed to make_rel().

Details

make_rel() is used to retain the relative height proportions between spectra while avoiding the large numbers that can result from some spectral instruments.

Value

make_rel() return numeric vectors (if vector provided) or an OpenSpecy object with the normalized intensity data.
