ooacquire 0.1.2

This is the second release of package ‘ooacquire’. It is an important update as it include bug fixes and enhancements which have some (minor) effect on the calculated spectral values. The update also removes some spurious warnings and has additional documentation, although not yet in final form.This package allows the acquisition of spectral data from spectrometers from Ocean Optics connected through the OmniDriver run-time, which is available at no cost from Ocean Optics. The current version implements several corrections and measuring protocols unavailable elsewhere in a single modular framework. Some of these cannot be used off-the-shelf as they require the characterisation and calibration of each individual spectrometer, so as to obtain usable values for constants. However, once these constants are available they can be passed as data arguments without need to modify the package itself. Functions are provided for spectral irradiance, spectral transmittance and spectral reflectance measurements. As transmittance and reflectance measurements are normally done relative to reference objects the calibration requirements are less involved than for spectral irradiance.

The package is available through r4photobiology repository.

This article discusses an important issue about the use of P-values and complements the articles I linked to last year in posts at this site.
