R 3.4.0 released

R 3.4.0 was released some days ago. A compatibility update to RStudio is also available.

The repositories at this site and obviously also at CRAN now contain package binary distributions for R 3.4.x and R 3.3.x.

One major change in this release is that the JIT (just in time) compiler is enabled by default. I have not done any benchmarking yet.

I have written a page explaining how to upgrade your R installation.

The code examples in my book Learn R …as you learnt your mother tongue continue to work as expected. However not all the package updates for R 3.4.0 are yet in CRAN. In package ‘gganimate’ function gg_animate() has been renamed gganimate().

The code examples in our book R for Photobiology: Theory and recipes for common calculations run without problems. Due to recent updates to the packages in my R for Photobiology Suite, used in the book examples, fewer warnings than earlier are triggered.

photobiology 0.9.15

The main changes from version 0.9.14 the previous CRAN release, are:

Add methods na.omit() and na.exclude() for spectral objects (R’s default na.pass() and na.fail() can be used as is).

Laxen range test for cps in check_spct.cps_spct() and for counts in check_spct.raw_spct(), so as to avoid spurious warnings and/or errors.

Make waveband() with no arguments valid and use it as “null” return value.

Static website of documentation generated with package ‘pkgdown’ instead of ‘staticdocs’.

NOTE: The updated package is on CRAN.  (Binaries will be soon built.)

Talk at NOG2017

I gave today a talk on one possible way of using R package ‘ooacquire’. I used for the presentation a video with programmed pauses. The pauses are missing from this exported MP4 video file.
