The recently released ‘ggbreak’ package (= 0.0.3), by Guangchuang Yu and Shuangbin Xu, allows to add scale breaks to plots, an important feature previously unavailable for ggplots. Unfortunately, several geoms from ‘ggpp’ (<= 0.4.0) do not currently work well together with ‘ggbreak’, affecting also ‘ggpmisc’ (<= 0.4.0). In other words, insets and layer created with geoms based on npc pseudo aesthetics are added to all split subpanels. I will see if it is possible to get these packages to cooperate in the future.
All edits in this update are related to the debug geom and stats. Overall the edits aim at simplifying the interface and ensuring that the package works with recent versions of ‘ggplot2’. Because of the way ggplot works, geoms used as argument to stats may not see all default arguments, so a simpler interface makes use easier.
Changes compared to ‘gginnards’ 0.0.4:
geom_debug_npc()as a synonym for
geom_debug()to allow debugging of geoms supporting npc coordinates as defined in package ‘ggpp’.
stat_debug_panel()simplifying the output to the console. In particular avoid setting default aesthetics, change default for
head()as default for summaries .
head()as default for
- Revise part 1 of the User Guide.Some of these changes to default arguments and function parameters are code-breaking but of little consequence as these debugging functions are meant to be used interactively.

The main change is the split of package ‘ggpmisc’ into two packages. Starting from this version, package ‘ggpmisc’ focuses only on plot annotations related to model fits and statistical summaries. The new package ‘ggpp’ contains generally useful extensions to the grammar of graphics such as new geometries and position functions. As package ‘ggpmisc’ loads package ‘ggpp’ the migration should have minimal if any impact on users’ code. Package ‘ggpp’ will be most useful to authors of packages that currently import ‘ggpmisc’, including myself. It is good to be aware that the split almost exactly follows the subject matter of the two vignettes previously part of ‘ggpmisc’. When using ‘ggpmisc’, users will notice that some functions have migrated only when consulting the documentation.
Compared to ‘ggpmisc’ 0.3.9, the following changes have been introduced. New justification styles have being implemented to complement
position_nudge_center(). They are supported in
geom_marging_grob(). In the current implementation all rows in
data should contain the same
vjust value when using the new types of justification described here, this seems reasonable as they compute the individual justification values from the data. All other justification values, either
character do not have this restriction and can be used as in geoms from ‘ggplot2’. These new features may change in the near future.
- Implement justifications
"inward_median"so that outward and inward are with respect to the centroid of the data instead of to the middle of the x or y scales. This should be useful in combination with
- Implement justifications
"inward_nnn"so that outward and inward are with respect to the number resulting from applying
as.numeric()to the characters that replace
nnn. For example strings like
"outward_-3e-2"are supported. This should be useful when manual tweaking is desired. As special cases
"inward_0"apply justification outward and inward with respect to the origin. This should be useful for biplots used for PCA and similar cases with arrows radiating out of the origin. (The
"inward"justification implemented in ‘ggplot2’ is relative to the middle of the x or y scales.)
compute_npcy()to support multiple steps per group (needed in ‘ggpmisc’).
- Fix problem related to
"inward"justification of text labels when
angleaesthetic takes values < -45 or > 45 degrees. This code change alters how old plots are rendered if text labels have been rotated by more than 45 degrees.
- [‘ggplot2’, ‘ggrepel’] The problem with angle was a “bug” in ‘ggplot2’ also present in ‘ggrepel’. A pull request for
ggplot2::geom_text()has been submitted and merged. This is now in the ‘ggplot2’ 3.3.4 milestone retaining consistent behaviour between ‘ggplot2’, ‘ggrepel’, ‘ggpp’ and ‘ggpmisc’.

Acknowlegements: 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 these two packages. I thank Mark Neal for the suggestion that lead to the new statistic
stat_quant_eq() and for his help during its testing. I thank Stackoverflow users ganidat and Tiptop for enhancement ideas.
Documentation web sites at https://docs.r4photobiology.info/ggpmisc/ and https://docs.r4photobiology.info/ggpp/ include 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 package ‘ggpp’ (0.4.0) is in CRAN and updated ‘ggpmisc’ (0.4.0) is on its way to CRAN. The latest development versions of both packages can be installed from GitHub.
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
- Fix handling of
na.rm = TRUEin
- Revise the computation of the default for
cps2Rfr()so that it takes into account the relative signal in
the reference spectrum.
- Add parameter
cps2irrad()so that corrupted too-short spectra can be converted if the location of missing pixels
- Add row-wise summaries for
- Add support of multiple spectra in long form to
- Add warning for handling of multiple spectra in long form to
