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 version0.10.5 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
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.
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().
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.
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)) +
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"))
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.
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.
