R 4.2.0

For Windows users the most significant changes are that now the binary distribution contains only a 64 bit executable. A new build chain is used and Rtools 4.2 is required to build from sources packages that include C, C++ or FORTRAN code. As is always the case, all CRAN packages are tested on CRAN itself.

Relevant to all operating systems the recently added pipe oprerator (|>) now supports the use of the underscore (_)  as a placeholder on the rhs of the operator.

1:10 |> mean() |> round()

1:10 |> mean(x = _) |> round(x = _)

These two statements are equivalent, but _ makes it possible to pipe by name the value returned by the lhs into any parameter on the rhs.

There are also some improvements to the ‘grid’ package adding flexibility to pattern and gradient fills and masks, which are recently added features. They are yet to be well supported by ‘ggplot2’.

ooacquire 0.2.3

Main changes since version 0.2.2 are:

  • Implement support for on-the-fly retrieval of instrument descriptor and calibration data from EEPROM when calibration is not available as R objects: update acq_irrad_interactive() and the functions it uses to retrieve and save calibration data.  (Similar updates are pending for the other data acquisition functions).
  • Update calibration data for MAYP11278 and MAYP112785.
  • Test with old USB2000 spectrometer.

NOTE: This package is NOT available through CRAN.

This package is available through the r4photobiology repository  and through GitHub.

INSTALLATION:

Note: this version needs the recently released ‘rOmniDriver’ version 0.1.14 or later, so if this package is already installed it may need to be updated before updating or installing ‘ooacquire’ 0.2.3.

  1. From the binary or source packages of the released version from the CRAN-compatible repository at http://r.r4photobiology.info/.
  2. From sources of the under development version retrieved from the Git repository at GitHub.

ooacquire 0.2.2

During the last two years development has continued at a slow pace. Most changes are to the functions for interactive acquisition of spectra, correction of bugs and tracking to changes in packages from which imports are made. Testing was done with new OmniDriver releases. Some data examples have been added and also replaced. Some progress with the vignettes has been done. However, the documentation still needs work.

One visible change is the move of the Git repository from Bitbucket to GitHub. Package ‘rOmniDriver’ has also been moved to GitHub and its documentation updated to reflect this.

Starting from this release, the changelog is included in the online documentation at http://docs.r4photobiology.info/ooacquire/.

R 4.0.3

A minor update to R was released recently as version 4.0.3. As always it is recommended to keep R up-to-date. R for photobiology packages and their dependencies are not affected by this are previous updates and pass checks on R >= 3.6.0.
