rename for hyperSpec objects

rename extra data columns of hyperSpec objects. Special column $spc contains the spectra matrix. Unlike dplyr::select() dplyr::rename() keeps all the variables of the data frame intact. However, if $spc is renamed, the result is an error instead of a hyperSpec object.

# S3 method for hyperSpec
rename(.data, ...)

Arguments

.data

A data frame, data frame extension (e.g. a tibble), or a lazy data frame (e.g. from dbplyr or dtplyr). See Methods, below, for more details.
