  when previsously missing.
* Add some examples to documentation.

## photobiologySun 0.4.1

## photobiologySun 0.3.5

*  Rebuild with 'photobiology' 0.8.5.

## photobiologySun 0.3.4

*  Add `gap.mspct` data.

## photobiologySun 0.1.4

*  Updated required version of 'photobiology' package.

## photobiologySun 0.1.3

*  Edited the script to use `.spct` as name tag for spectra instead of `.dt`.
*  Rebuilt with current versions of 'photobiology' and 'MayaCalc' packages.
*  Edited the vignette to make use of the new function `plot.source.spct()` specializing the `plot()` generic.

## photobiologySun 0.1.2

*  Now spectra are in `data.frame` and `data.table` compatible `"source.spct"` objects.
