ggpmisc 0.3.0

R packagesLeave a comment

A major update to ‘ggpmisc’ (0.3.0) follows availability of the update of ‘ggplot2’ (3.0.0) and the release of the new package ‘gginnards’ (0.0.1) through CRAN. Package documentation available at https://docs.r4photobiology.info/ggpmisc/ as a web site.

Functions earlier included in ‘ggpmisc’ (< 0.3.0) related to debugging and low level manipulation of ggplot objects have been moved to package ‘gginnards’. The functions that remain in ‘ggpmisc’ (>= 0.3.0) are related to annotation of plots with fitted-model equations, fit diagnosis, ANOVA and summary tables, highlighting and labelling of peaks and valleys in curves, and local density-based highlighting or labelling in scatter plots.  Additionally specializations of the ggplot() constructor allow on-the-fly conversion of time-series and geom_table() makes it possible to add tables to plots respecting the the Grammar of Graphics paradigm.

The enhancements in this update to ‘ggpmisc’ are made possible by changes to ‘ggplot2’ (>= 3.0.0) made while adding support for sf shape data. Not all extensions to ‘ggplot2’ have been updated yet to be compatible with the new version of ‘ggplot2’ so if you need them, you may need to wait before updating to ‘ggplot2’ (3.0.0) and consequently also before updating to this version of ‘ggpmisc’.

This time I include some example plots taken from the documentation of the package. In all cases annotations are generated automatically, but formatting is flexible. Larger plots are linked to the thumbnails.

Main changes since ‘ggpmisc’ (0.2.17) the previous CRAN release.

  • Add geom_table() a geom for adding a layer containing one or more tables to a plot panel.
  • Add stat_fit_tb() a stat that computes a tidy tabular version of the summary table or ANOVA table from a model fit.
  • Add support for "weight" aesthetic in stat_poly_eq() so that weights can be passed to lm() (fixing bug reported by S.Al-Khalidi).
  • Add support for column selection and renaming to stat_fit_tb().
  • Add new statistic stat_fmt_tb() for formatting of tibbles for addition to plots as tables.
  • Rename stat_quadrat_count() into stat_quadrant_count() (fix miss-spelling).
  • Move debug stats and geoms to package ‘gginnards’.
  • Move plot layer manipulation functions to package ‘gginnards’.
  • Revise vignettes.

NOTE: The new version of ‘ggpmisc’ is on its way to CRAN and should be available for download later in the week.

from data to Viz is a new web site related to data analysis and R. Its aim is to make it easier to choose among different types of data visualisations. It looks beautiful, is easy to navigate, includes “trees” displaying a classification of visualizations and multiple individual examples with the corresponding R code.  Highly recommended!

gginnards 0.0.1

Package update / R packages / SoftwareLeave a comment

Package ‘gginnards’ is now in CRAN. This new package contains functions removed from ‘ggpmisc’ at version 0.3.0. The package was split as the audience the different functions are intended for is different: ‘gginnards’ is for those needing tools for programming ‘ggplot2’ extensions or wanting to learn how ggplots work. Most importantly, the functions now in ‘gginnards’ cannot be expected to survive with unchanged functionality across major updates to ‘ggplot2’, and importing them into other packages is strongly discouraged.

In contrast the functions retained in ‘ggpmisc’ and the new ones added in version 0.3.0 are intended for users creating plots for data analyses and reports. I am committed to maintaining ‘ggpmisc’ in the long term while striving to retain backwards compatibility as much as possible.

Documentation web site at http://docs.r4photobiology.info/gginnards/ includes all help pages, with output from all examples, and vignettes in HTML format.
NOTE: The package is available through CRAN.
