siWl: Isolate single wavelength

In bpollner/aquap2: Multivariate Data Analysis Tools for R including Aquaphotomics Methods

Isolate single wavelength

Description

Generate a dataset with a single wavelength.

Usage

siWl(dataset, wl, getMax = FALSE)

Arguments

dataset	An object of class 'aquap_data' as produced e.g. by gfd.
wl	Numeric length one. The
getMax	Logical. Set to 'TRUE' to isolate the wavelength with the highest sum of absorbtion values.

Details

Provide the wavelength that should remain in the dataset in the argument wl. It is not ncecessary to exactly know the desired wavelength – if there is no direct match with the wavelength, the next best hit will be taken.

Examples

## Not run: 
fd <- gfd()
dataset_single <- siWl(fd, 1300) # to only leave wavelength 1300
dataset_single2 <- siWl(fd, getMax=TRUE) # to look for the wavelength with 
# highest sum of absorbtion values

## End(Not run)
