Methods for function rfe in package caret. Please refer to help pages in the caret-package for further information.
## S4 method for signature 'Speclib' rfe(x, y, cutoff = 0.95, returnData = TRUE, na.rm = FALSE, ...) ## S4 method for signature 'Nri' rfe(x, y, cutoff = 0.95, returnData = TRUE, na.rm = FALSE, ...) ## S4 method for signature 'Specfeat' rfe(x, y, cutoff = 0.95, returnData = TRUE, na.rm = FALSE, ...) get_rfe(x)
x |
Object of class |
y |
A numeric or factor vector containing the outcome for each sample. If missing, the response variable set by |
cutoff |
The cutoff value of the correlation coefficients between response variables. |
returnData |
Logical. If TRUE, the updated object of |
na.rm |
Logical. If TRUE, all variables are excluded which contain at least one non-finite value. |

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