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’.
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’.
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.
