quantile.spectra

<code>quantile</code> computes quantiles by band and returns them as `spectra`.

Input/Output, processing and visualization of spectra taken with different spectrometers, including SVC (Spectra Vista), ASD and PSR (Spectral Evolution). Implements an S3 class 'spectra' that other packages can build on. Provides methods to access, plot, manipulate, splice sensor overlap, vector normalize and smooth spectra.

quantile.spectra function

<dl><dt>x</dt>
<dd>spectra object. Must have at least the same number of sample that
length(probs) has.</dd>
<dt>probs</dt>
<dd>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.</dd>
<dt>na.rm</dt>
<dd>remove NAs before computing quantiles? Defaults to TRUE</dd>
<dt>names</dt>
<dd>names for each quantile spectrum. If NULL (default), names are set
to `probs`. A char vector should otherwise be given. Recycled.</dd>
