hs_contrast: Contrast plot for Raman spectra

In CMET-UGent/MicroRaman: Phenotyping of microbial Raman spectroscopy data

Description

A way to visualize contrasts between Raman spectra from different samples in an existing hyperSpec object

Usage

hs_contrast(hs.x, comp1, comp2, plot = TRUE)

Arguments

hs.x	a hyperSpec object
comp1	numeric (any length) or boolean (TRUE/FALSE - length equal to number of spectra in hs.x) vector with sample names from one side of the comparisons
comp2	numeric (any length) or boolean (TRUE/FALSE - length equal to number of spectra in hs.x) vector with sample names from the other side of the comparisons
plot	a logical indicating whether or not the constrasts should be plotted (defaults to TRUE)

Value

a dataframe containing the contrast values between the averaged spectra

Examples

## Short example
data("hs_example")

# Preprocess
hs_example <- hs_preprocess(hs_example)

# Run contrast comparison
hs.cont <- hs_contrast(hs_example, comp1 = c(1:4), comp2 = c(8:20))
