Datasets and Code Examples from P. J. Aphalo's "Learn R" Book
Data, scripts and code from chunks used as examples in the book "Learn R: As a Language" by Pedro J. Aphalo. ISBN 9780367182533 (pbk); ISBN 9780367182557 (hbk); ISBN 9780429060342 (ebk).
Plant Photobiology Related Functions and Data
Provides functions for quantifying visible (VIS) and ultraviolet
(UV) radiation in relation to the photoreceptors Phytochromes,
Cryptochromes, and UVR8 which are present in plants. It also includes data
sets on the optical properties of plants. Part of the 'r4photobiology'
suite, Aphalo P. J. (2015)
Response Data for Light Sensors
Spectral response data for broadband ultraviolet and visible
radiation sensors. Angular response data for broadband ultraviolet and visible
radiation sensors and diffusers used as entrance optics. Data obtained from
multiple sources were used: author-supplied data from scientific research
papers, sensor-manufacturer supplied data, and published sensor
specifications. Part of the 'r4photobiology' suite Aphalo P. J. (2015)
Spectral Data for Light-Emitting-Diodes
Spectral emission data for some frequently used light emitting
diodes available as electronic components. Part of the 'r4photobiology'
suite, Aphalo P. J. (2015)
Spectral Irradiance Data for Lamps
Spectral emission data for some frequently used lamps including
bulbs and flashlights based on led emitting diodes (LEDs) but excluding
LEDs available as electronic components. Original spectral irradiance data
for incandescent-, LED- and discharge lamps are included. They are
complemented by data on the effect of temperature on the emission by
fluorescent tubes. Part of the 'r4photobiology' suite, Aphalo P. J. (2015)
Extensions to 'ggplot2' for Radiation Spectra
Additional annotations, stats, geoms and scales for plotting
"light" spectra with 'ggplot2', together with specializations of ggplot()
and autoplot() methods for spectral data and waveband definitions
stored in objects of classes defined in package 'photobiology'. Part of the
'r4photobiology' suite, Aphalo P. J. (2015)
Waveband Definitions for UV, VIS, and IR Radiation
Constructors of waveband objects for commonly used biological
spectral weighting functions (BSWFs) and for different wavebands describing
named ranges of wavelengths in the ultraviolet (UV), visible (VIS)
and infrared (IR) regions of the electromagnetic spectrum. Part of the
'r4photobiology' suite, Aphalo P. J. (2015)
Photobiological Calculations
Definitions of classes, methods, operators and functions for use
in photobiology and radiation meteorology and climatology. Calculation of
effective (weighted) and not-weighted irradiances/doses, fluence rates,
transmittance, reflectance, absorptance, absorbance and diverse ratios and
other derived quantities from spectral data. Local maxima and minima: peaks,
valleys and spikes. Conversion between energy-and photon-based units.
Wavelength interpolation. Astronomical calculations related solar angles and
day length. Colours and vision. This package is part of the 'r4photobiology'
suite, Aphalo, P. J. (2015)
Data for Sunlight Spectra
Data for the extraterrestrial solar spectral irradiance and ground
level solar spectral irradiance and irradiance. In addition data for
shade light under vegetation and irradiance time series from different
broadband sensors. Part of the
'r4photobiology' suite, Aphalo P. J. (2015)
Read Spectral and Logged Data from Foreign Files
Functions for reading, and in some cases writing, foreign files
containing spectral data from spectrometers and their associated software,
output from daylight simulation models in common use, and some spectral
data repositories. As well as functions for exchange of spectral data with
other R packages. Part of the 'r4photobiology' suite,
