This is the first version submitted to CRAN for the book as published in the R Series.

Versions starting from 1.0.0 are for the book as published in the R Series. Earlier versions were for various partial drafts of the book, as pre-published through LeanPub. The book was published a few of weeks ago, but shipping has started in the last few days.

NOTE: The updated package is on its way to CRAN.

photobiology 0.10.5

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

This update adds a new attribute to objects of class response_spct to enable storage of metadata to distinguish action spectra from response spectra. All other changes are tweaks to make use easier or are minor bug fixes, which do not add important new functionality.

Changes from version 0.10.4 the most recent CRAN release, are:

New

Implement attribute "response.type" to distinguish between response spectra and action spectra stored in response_spct objects.
Add methods setResponseType() and getResponseType().
Add method drop_user_cols() to remove user-defined columns from spectra.
Add method collect2mspct() and rename method uncollect() into uncollect2spct().
Add convenience function spct_metadata() to query the value of metadata attributes.
Revise add_attr2tb() expanding support to all metadata attributes.
Revise smooth_spct() methods adding new parameter wl.range.
Revise compare_spct() function to accept scaled and normalized spectra with a warning (instead of triggering an error).

Fixed

Make the pre-computed color data private.
Revise rbindspct() to gracefully handle duplicate member names in its input.
Revise smooth_spct() methods to fix bug in handling of strength in "custom" method.

NOTE: The updated package is on its way to CRAN.

My new book was published on 28 July. Within the next few days I will make available on-line supplementary material, and explain how I created in R the word cloud in the front cover of the book. The word list I used is that for the R index from the book. I typeset the book using LaTeX. It is currently available from the publisher through the book’s web page.
