quantile.spectra: Compute spectra quantiles

In spectrolab: Class and Methods for Spectral Data

Compute spectra quantiles

Description

quantile computes quantiles by band and returns them as 'spectra'.

Usage

## S3 method for class 'spectra'
quantile(
  x,
  probs = c(0.025, 0.25, 0.5, 0.75, 0.975),
  na.rm = TRUE,
  names = NULL,
  ...
)

Arguments

x	spectra object. Must have at least the same number of sample that length(probs) has.
probs	Probabilities to compute quantiles. Must be a vector of numerics between 0.0 and 1.0. Defaults to c(0.025, 0.25, 0.5, 0.75, 0.975). Duplicated probs will be removed.
na.rm	remove NAs before computing quantiles? Defaults to TRUE
names	names for each quantile spectrum. If NULL (default), names are set to 'probs'. A char vector should otherwise be given. Recycled.
...	other arguments passed to quantile.

Value

spectra object with one spectrum for each prob
