caret::sbf: Methods for Function sbf

Description

Methods for function sbf in package caret.

Usage

"sbf"(x, y, cutoff = 0.95, returnData = TRUE, ...)
"sbf"(x, y, cutoff = 0.95, returnData = TRUE, ...)
"sbf"(x, y, cutoff = 0.95, returnData = TRUE, ...)
get_sbf(x)

Arguments

x

Object of class Speclib, Nri or Specfeat. For get_sbf, x must be the output of sbf as Speclib or Nri.

y

A numeric or factor vector containing the outcome for each sample. If missing, the response variable set by setResponse is used.

cutoff

The cutoff value of the correlation coefficients between response variables.

returnData

Logical. If TRUE, the updated object of x is returned, otherwise only the result of sbf is returned.

...

Further aruments passed to sbf.

Value

If returnData == TRUE, an object of class Speclib or Nri, otherwise an object of class sbf. Note that if x is an object of class Specfeat, the function returns an object of class Speclib containing the relevant transformed band values.

Examples

## Not run: 
# data(spectral_data)
# 
# ## Set response variable (Chlorophyll content)
# spectral_data <- setResponse(spectral_data, "chlorophyll")
# 
# ## Set additional predictor variables from the attributes
# spectral_data <- setPredictor(spectral_data, "season")
# 
# ## Selection by filtering
# ## Note that this may take some time!
# sbf_res <- sbf(spectral_data)
# 
# get_sbf(sbf_res)
# 
# plot(get_sbf(sbf_res))
# ## End(Not run)
