photobiologyInOut 0.4.19

Package updateLeave a comment

The main changes from version 0.4.18 the previous CRAN release, are:

  • Track reverted previous code breaking change in ‘readr’ (>= 1.3.0).

Because of a code breaking change in package ‘readr’ this version of ‘photobiologyInOut’ requires ‘readr’ >= 1.3.0 to be installed. Function read_oopi_data() from ‘photobiologyInOut’ < 0.4.19 will not work as expected under ‘readr’ >= 1.3.0. (I thank Jim Hester for making a pull request that solved the problem introduced by the change in ‘readr’.)

photobiology 0.9.25

Package update / R packagesLeave a comment

Changes from version 0.9.24, the most recent CRAN release, are:

  • Fix bug in merging of attributes which was causing errors in operations between spectra which had specific differences in their attributes.
  • Fix incompatibility with tibble (>= 2.0.0).

Documentation web site at http://docs.r4photobiology.info/photobiology/ includes all help pages, with output from all examples, and vignettes in HTML format.
NOTE: The updated package is on its way to CRAN.

ooacquire 0.1.6

Data acquisition / Data analysis / Mehods / Package updateLeave a comment

Improvements aiming at continuing the expansion of the support of different Ocean Optics spectrometers and of  additional measurement methods.

  • Update acq_irrad_interactive() adding alternative user-interface modes, allowing users to set comment and what.measured attributes, and to construct collections of spectra.
  • Add pre-built calibrations and methods for additional FLAME-S instruments.
  • Improve algorithm for automatic tuning of integration time to achieve faster convergence.
  • Fix various minor bugs.
  • Update vignettes.
  • Test against OmniDriver 1.2.56
  • Update read_ooov_files() for compatibility with ‘readr’ >= 1.2.0 which is now required

Add support for measurement of pulsed light sources (under development)

The new features described below are under development, subject to change without previous notice and not yet well tested!! (double-check any results and please report any bugs by raising an issue!)

Implement support for measuring output from xenon flashes, including use of such flashes as light sources for measurement of spectral transmittance and reflectance. Use of multiple exposures per integration is also supported and the number of exposures stored as metadata is used during later processing. In the case of pulsed light sources the first conversion of RAW spectra is into counts per exposure, and instead of spectral irradiance spectral fluence per exposure is computed. All changes are backwards compatible with raw data acquired with earlier versions of ‘ooacquire’ and the user interface remains unaltered for the measurement of continuous light sources.

  • Add function acq_fluence_interactive() for measuring spectral fluence of pulsed light sources.
  • Add acq_fraction_pulsed_interactive() for measuring transmittance and reflectance using a pulsed light source.
