ggspectra 0.3.6

Package documentation web site at: https://docs.r4photobiology.info/ggspectra/

The changes from version 0.3.5, the current CRAN release, are:

New

  • Support for computation of colors using other chromaticity coordinates than the color matching function (CMF) for human vision.
  • stat_spikes(), useful for highlighting and labeling spikes in spectra.
  • Fitted peaks and valleys (experimental).
  • Annotations "wls" and "wls.labels" in autoplot() methods.
  • Update decoration() to support "wls" and "wls.labels".
  • Compatibility with ‘dplyr’ (>= 1.0.0).
  • Track changes in ‘photobiology’ 0.10.1 and 0.10.2.

Bugs fixed

  • Fix two bugs in ggplot() method for class object_spct.

NOTE: The updated package is on its way to CRAN.

photobiology 0.10.2

Package documentation web site at: https://docs.r4photobiology.info/photobiology/

This new update comes on the steps of the two previous ones (0.10.0, 0.10.1) and fixes a few bugs found since.

Changes from version 0.10.1 the most recent CRAN release, are:

Bugs fixed

  • color_of() was failing in some cases when it should not.
  • merge2object_spct(), merge_attributes(), interpolate_spct(), [ ] were in certain cases dropping attributes, in most but not all cases only filter.properties.
  • White LED example spectra may have had attributes inconsistently set.
  • Additional test cases were added (a suite of 4165 automatic test cases is used before release).

R 4.0.0

R version 4.0.0 has been released today. In the case of complex ggplots there is a noticeable improvement in performance. As is normal in CRAN, packages are automatically tested. Most of the packages I have developed are in CRAN, and you can easily see their check status at any time in the page where they are listed. At the moment there are warnings under OS-X affecting the building of vignettes for many different packages in addition to several of my own, all with the same message. I suspect this problem is related to ‘knitr’ or ‘roxygen2’.

ggpmisc 0.3.4

This version (0.3.4) adds to stat_poly_eq() the ability to return F-value and P-value in addition to the equation of the polynomial, R2, AIC and BIC available in earlier versions of ‘ggpmisc’. The package code and examples have been updated to avoid the use of functions and methods that have been deprecated in recent updates to ‘ggplot2’.

library(ggpmisc) # version >= 0.3.4 !!
ggplot(mtcars, aes(x = wt, y = mpg, colour = factor(cyl))) +
  geom_smooth(method="lm") +
  geom_point() +
  stat_poly_eq(formula = y ~ x,
               aes(label = paste(stat(f.value.label), stat(p.value.label), 
                                 sep = "*`,`~")),
               parse = TRUE,
               label.x.npc = "right") +
  theme_bw()

The code above produces the plot below.

Acknowlegement: This update as well as the very start of the development of this package has been triggered by some great questions posted at stackoverflow. These questions and answers can be found with a search for the tag [ggpmisc] at stackoverflow. When asking questions or help related to this package, please tag your question.

Documentation web site at http://docs.r4photobiology.info/ggpmisc/ includes all help pages, with output from all examples, and vignettes in HTML format.

NOTE: The new version of the package is on its way to CRAN.
