The main changes from version0.4.16 the previous CRAN release, are:
Add new function read_oo_jazpc() to read transmittance (%) and reflectance (%) from processed data output by Ocean Optics’ Jaz modular spectrometer.
Fix bug that made CRAN tests to fail under “oldrel” : decoding of dates in fmi and TUV import functions not always returned POSIXct objects under R (=3.4.4) triggering errors in downstream code. (Possible underlying problem: class of returned values from some functions from package ‘lubridate’ seems to depend on the R version.)
Changes from version0.9.23, the most recent CRAN release, are:
Fix major bug in internally used method merge_attributes(), accidentally introduced in version 0.9.23, which in certain cases triggered fatal errors when using operators or other methods taking two spectra as arguments. This also affected indirectly package ‘ooacquire’.
Add method wls_at_target() implementing search and interpolation of wavelengths at which the spectral quantity matches a target value. This method is implemented for all spectral classes and collections of spectra, except raw_spct, chroma_spct and object_spct and corresponding collections.
Add (experimental) support for spectral measurements where the exposure time is dependent on the light source instead of on the integration time settings in the spectrometer such as when measuring the light output from xenon-tube flashes.
If you are using version 0.9.23, please, do update to this new version, to avoid being affected by the now fixed bug.
Changes from version0.9.22, the most recent CRAN release, is:
Bug fix: Ensure that getWhenMeasured() always returns an object of class POSIXct. Avoids occasional crashes in ‘PhotobiolgyInOut’.
Add scale.factor as formal parameter to methods irrad(), q_irrad(), e_irrad(), response(), q_response() and e_response(). Previous behaviour remains the default.
Change default value for parameter idx in the various summary methods for collections of spectra. Also add parameter idx to “add attributes to tibble” methods. The new default argument does not affect the default behaviour of the methods. The change in handling of idx = NULL, the old default might break old code in exceptional cases when idx = NULL was passed explicitly in user code instead of relying on it being the default.
Rewrite the “get” methods for attributes using a simpler, and possibly faster approach.
Add parameter sep to function convolve_each(). Previous behaviour remains the default.
