Changes for version 0.7-3 [2018-04-01]

• add new function actinometric()
• add new function as.data.frame()
• add new function atmosTransmittance()
• add new function CCTfromuv()
• add new functions is.actinometric() and is.radiometric()
• add new function ptransform(), and use it to compute BT.709.RGB and Adobe.RGB
• add new function emulate()
• add new function as.colorSpec()
• add new vignette Emulation of one Camera by another Camera
• add new vignette Photon Counting
• add built-in object luminsivity.1nm
• add new spectra files moths.txt and sunglasses.txt
• add new spectra files Philips-HPS.txt, solar-exposure.txt, P4-phosphor-JEDEC.txt, and Cree-LED.txt
• add "featured functions" to all vignettes
• spectral quantity power is deprecated, and replaced by energy. power still works, but will eventually be removed.
• in colorSpec(), add argument specnames
• in resample(), add arguments extrapolation and clamp
• in photometric() add arguments photopic, scotopic, and multiplier
• in cs.options(), partial matching of the option name is enabled
• in radiometric(), add arguments multiplier and warn
• in metadata()<- add argument add
• in extradata()<- add argument add, and allow value to be NULL
• in product(), add argument integration, and added an ambiguity warning
• in summary(), the displayed Integral now works for irregular wavelengths
• in summary(), print attribute ptransform if present
• in plotPatchesRGB(), allow background to be linear RGB, fixed bug for shape
• in planckSpectra(), added new argument c2
• in computeCCT() and CCTfromXYZ() and CCTfromuv(), added new arguments method, strict, and c2
• in computeCRI(), CCT is now computed with method='lm'
• in calibrate(), fix special case when there is only 1 spectrum
• in plot(), fixed warning when ylab is an expression
• in bind(), fixed bug when binding the extradata
• colorSpec options are now stored in the global option list, and start with 'colorSpec.'
• in vignette Phenol Red - pH Indicator, now display RGB matrix explicity, both before and after scaling
• additions and improvements to colorSpec User Guide
• now Imports package minpack.lm

Changes for version 0.6-2 [2017-12-03]

• bug fix: print.colorSpec() and summary.colorSpec() were sending output to stderr(), instead of stdout()
• improved reading of CGATS files with standard whitespace convention
• in all sample CGATS files, changed spaces in field names to underscores

Changes for version 0.6-1 [2017-11-16]

• renamed proofs.Rmd to proofs.txt - to avoid "Files named as vignettes but with no recognized vignette engine:"

Changes for version 0.6 [2017-11-16]

• updated colorSpec-guide.odt to colorSpec-guide.Rmd (rmarkdown v 2)
• for physical models in colorSpec-guide.Rmd, replaced $L^2$ by $L^\infty$ and $L^1$, and added proofs
• added 4 new files with reflectance spectra
• added new function interpolate()
• added new vignette - an investigation of phenol red
• in plot.colorSpec(), compute automatic margin line for ylab, depending on the width of y-axis labels
• in bind.colorSpec(), add check for distinct specnames()
• bug fix to "extradata<-.colorSpec"; specnames() was not being preserved
• in logging mechanism, changed output from stdout() to stderr(), for better compatibility with RStudio
• export function readCGATS(), for easy access to non-spectral data in CGATS files

Changes for version 0.5-3 [2016-05-16]

• Fixed filename case problem on non-Windows platforms and resubmitted

Changes for version 0.5-2 [2016-05-15]

• Fixed 2 NOTEs and resubmitted
