Old repository at mv.helsinki.fi closed

For several months the main repository for the packages has been located at https://www.r4photobiology.info/R but the old repository remained available. From today the old repository has closed. So, if you were still using it, you will need to switch to the new address. Apart for their URL the repositories have been identical until a couple of weeks ago when I stopped updating the contents of the old repository.


photobiology 0.6.8

Functions sunrise_time(), noon_time(), sunset_time(), day_length(),night_length()andday_night()gain formal parameter‘unit.out’`,
but its default value preserves earlier behaviour.

New generic functions peaks() and valleys().

subset() methods for spectral objects gain a new parameter 'idx'. (This a workaround until a way of wrapping [ operator from data.table is found.) During subsetting, tags are removed from the returned spectrum.

Functions is.photon_based(), is.energy_based(), is.absorbance_based() and is.transmittance_based() have been renamed by replacing the dot with an underscore for consistency with other functions not test for object class.

Fixed bug in trim_waveband().

photobiologygg 0.3.4

annotate_plot() now passes arguments 'angle', 'hjust' and 'vjust' to annotate_waveband() in the case of labels.

NOTE: Sources, and Windows binaries for R 3.1.x and R 3.2.x, are now available in the repository.

Handbook on photobiological calculations with R

A handbook on how to do calculations used in photobiological research with R is under preparation. The handbook will describe the use of our suite of R packages and also of functions from base R and packages from CRAN. Authors are Andreas Albert, Titta Kotilainen and myself. Further details, and possibly an early draft for download will be soon available.

UseR!2015 Conference in Aalborg

useR! logo

I will give a talk at the UseR! conference describing the packages. This will be the first public announcement of the packages, as I consider that the packages, although still under development are now ready for testing by a broader audience and careful use in research and other non-life- or health-threatening measurements and data analysis.

The abstract is available at: http://user2015.math.aau.dk/contributed_talks#153

The presentation slides will be available for download after the conference.
