photobiology 0.10.6

The package documentation web site at https://docs.r4photobiology.info/photobiology/ includes a changelog with information for each release since version 0.1.0.

This release includes fixes to several minor bugs that were reported during the last seven months. In addition to these fixes new specializations of existing methods were added to improve the consistency across the different methods and classes. The Git repository was recently moved from Bitbucket to GitHub and continuous integration using Git actions set up.

Changes from version 0.10.5 the most recent CRAN release, are:

  • Fix boundary-condition bug in msmsply().
  • Fix handling of na.rm = TRUE in find_peaks().
  • Revise the computation of the default for dyn.range in cps2Tfr() and cps2Rfr() so that it takes into account the relative signal in
    the reference spectrum.
  • Add parameter missing.pixs to cps2irrad() so that corrupted too-short spectra can be converted if the location of missing pixels
    is known.
  • Add row-wise summaries for raw_mspct and cps_mspct objects.
  • Add support of multiple spectra in long form to irrad(), e_irrad(), q_irrad(), q_ratio(), e_ratio(), qe_ratio(), eq_ratio(), absorbance(), absorptance(), trasmittance(), reflectance() methods.
  • Add warning for handling of multiple spectra in long form to integrate_spct() method.

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

ggpmisc 0.3.9

Package ‘ggpmisc’ focuses mainly on plot annotations. The new version fixes minor bugs and adds a major new feature: position functions for data aware nudging. These nudge functions were born out of an exchange of ideas with Kamil Slowikowski, the author and maintainer of the very popular package ‘ggrepel’. We are currently considering how to make them compatible with geom_text_repel() and geom_label_repel().

The package documentation web site at: https://docs.r4photobiology.info/ggpmisc/ now includes a changelog, so I am brief here.

Changes from version 0.3.8, the most recent CRAN release, are:

  • Update the documentation of geom_plot().
  • [Under development!] Link repositioned text to its original position with a segment or arrow: geom_linked_text(). Except for
    the drawing of segments or arrows this new geometry behaves as ggplot2::geom_text() . Note: Segments and arrows are drawn only
    if the position function used returns both the repositioned and original coordinates.
  • Add support for advanced nudging: position_nudge_centre() and position_nudge_line() compute the direction of nudging and return
    both the nudged and original positions.
  • Add support for simple nudging: position_nudge_to() nudges to new user-supplied position(s); position_nudge_keep() nudges to
    position(s) based on user-supplies position shift. These functions return both nudged and original position(s).

Example: Nudging text labels away from a curve.

library(ggpmisc)

set.seed(16532)
df <- data.frame(
  x = -10:10,
  y = (-10:10)^2 + rnorm(21, 0, 4),
  l = letters[1:21]
)

ggplot(df, aes(x, y, label = l)) +
  geom_point() +
  stat_smooth(method = "lm", formula = y ~ poly(x, 2, raw = TRUE)) +
  geom_text(aes(y = y, label = l),
            position = position_nudge_line(method = "lm",
                                           x = 0.4, 
                                           y = 4,
                                           formula = y ~ poly(x, 2, raw = TRUE),
                                           direction = "split"))
The resulting plot.
Nudging of text labels away from a curve.

Roadmap: A split of the ‘ggpmisc’ package into two packages, one including the extensions to the grammar of graphics and another one including the functions related to plot annotations based on model fitting and statistical summaries seems necessary as the package has grown to include several extensions to the grammar of graphics that are generally useful. We are also working on improved inter-operation between ‘ggpmisc’ and ‘ggrepel’.

Acknowlegement: I thank Kamil Slowikowski for his contributions of ideas and for his willingness to keep the development of our packages coordinated. This update was done in part to address questions raised and reports of bugs by users, which I thank. The tag [ggpmisc] is in use at stackoverflow for questions related to the use this package. Please raise issues concerning bugs or enhancements to this package through GitHub at https://github.com/aphalo/ggpmisc/issues. Pull requests are also welcome.

Documentation web site at http://docs.r4photobiology.info/ggpmisc/ includes all help pages, with output from all examples, and vignettes in HTML format. The online vignettes include the output of all code examples, while the vignettes as included in the package, contain the output of only a subset of the code examples so as to keep the documentation at a reasonable size for package distribution.

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

gginnards 0.0.4

This update provides the following enhancements compared to ‘gginnards’ 0.0.3.

  • Track updates to package ‘ggplot2’, adding support and examples for plot layers created with geom_sf() .
  • Revise documentation.
  • Move git repository from Bitbucket to Github.
  • Set up Github action for CRAN-checks on Windows, OS X and Ubuntu.

ggpmisc 0.3.8

[27 January] ‘ggpmisc’ 0.3.8-1 is on its way to CRAN. The only change is correcting a mistake in a vignette. This was caused by the code-breaking change now highlighted below.

Package ‘ggpmisc’ focuses mainly on plot annotations. The new version adds fixes bugs and adds some minor feature. There are more significant changes to the documentation.

The package documentation web site at: https://docs.r4photobiology.info/ggpmisc/ now includes a changelog, so I am brief here.

Changes from version 0.3.7 the most recent CRAN release, are:

  • Move of the Git repository from Bitbucket to GitHub.
  • Revise stat_fit_glance(), stat_fit_augment(), stat_fit_tidy() and stat_fit_tb() to add support for additional methods and make it possible to pass additional arguments. This is a code-breaking change in that packages ‘broom’ and/or ‘broom.mixed’ need to be loaded explicitly with library().
  • Fix bugs related to handling of Date values.
