Subsetting spectra
Return subsets of spectra stored in class generic_spct or derived from
it.
## S3 method for class 'generic_spct' subset(x, subset, select, drop = FALSE, ...)
x |
object to be subsetted. |
subset |
logical expression indicating elements or rows to keep: missing values are taken as false. |
select |
expression, indicating columns to select from a spectrum. |
drop |
passed on to |
... |
further arguments to be passed to or from other methods. |
An object similar to x containing just the selected rows and
columns. Depending on the columns remaining after subsetting the class of
the object will be simplified to the most derived parent class.
This method is copied from base::subset.data.frame() but ensures
that all metadata stored in attributes of spectral objects are copied to
the returned value.
