spint: Interpolation for Intermediate Values of a Matrix of...

In spftir: Pre-Processing and Analysis of Mid-Infrared Spectral Region

Description

Allow the interpolation of intermediate values of a matrix of mid-infrared spectra.

Usage

spint(spectra, n = 1)

Arguments

spectra	matrix. The matrix of FTIR spectra. The first row corresponds to wavenumber; the remaining rows corresponds to absorbances.
n	numeric. Number of interpolated values between two variables. Defaults to 1.

Value

A matrix spectra with interpolated values. The first row corresponds to wavenumber; the remaining rows corresponds to absorbances.

data(spData)
# Convert data frame to matrix
spectra <- as.matrix(t(spData))
