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)
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,
Aphalo P. J. (2015)
Spectral Transmittance and Spectral Reflectance Data
Spectral 'transmittance' data for frequently used filters and
similar materials. Plastic sheets and films; photography filters;
theatrical gels; machine-vision filters; various types of window glass;
optical glass and some laboratory plastics and glassware. Spectral
reflectance data for frequently encountered materials. Part of the
'r4photobiology' suite, Aphalo P. J. (2015)
Create Interactive Web Graphics via 'plotly.js'
Create interactive web graphics from 'ggplot2' graphs and/or a custom interface to the (MIT-licensed) JavaScript library 'plotly.js' inspired by the grammar of graphics.
Colorblind-Friendly Color Maps for R
Color maps designed to improve graph readability for readers with common forms of color blindness and/or color vision deficiency. The color maps are also perceptually-uniform, both in regular form and also when converted to black-and-white for printing. This package also contains 'ggplot2' bindings for discrete and continuous color and fill scales. A lean version of the package called 'viridisLite' that does not include the 'ggplot2' bindings can be found at < https://cran.r-project.org/package=viridisLite>.
Colorblind-Friendly Color Maps (Lite Version)
Color maps designed to improve graph readability for readers with common forms of color blindness and/or color vision deficiency. The color maps are also perceptually-uniform, both in regular form and also when converted to black-and-white for printing. This is the 'lite' version of the 'viridis' package that also contains 'ggplot2' bindings for discrete and continuous color and fill scales and can be found at < https://cran.r-project.org/package=viridis>.
Efficient Estimation of Covariance and (Partial) Correlation
Implements a James-Stein-type shrinkage estimator for
the covariance matrix, with separate shrinkage for variances and correlations.
The details of the method are explained in Schafer and Strimmer (2005)
