ggpmisc 0.2.8 (CRAN release)

The main changes from version 0.2.7 the previous CRAN release, are:

Enhance stat_poly_eq() so that 1) position of labels according to npc (relative positions using normalized coordinates), as well as by named positions "top", "bottom", "right", "left" and "center" is now implemented; 2) when grouping is present, suitable vjust values are computed to automatically position the labels for the different groups without overlap. Default label positions are now relative to the range of each panel’s x and y scales, eliminating in most cases the need to manually tweak label positions for groups.

Add stat_fit_glance() uses package ‘broom’ for maximum flexibility in model function choice when wanting to add labels based on information from a model fit, at the expense of very frequently having to explicitly set aesthetics, and always having to add code to do the formatting of the values to be used in labels. Label positioning is as described above for stat_poly_eq().

Add stat_fit_deviations() for highlighting residuals in plots of fitted models. This statistic currently supports only lm() fits. By default geom "segment" is used to highlight the deviations of the observations from a linear fitted model.

Add stat_fit_residuals() for plotting residuals from a fitted model on their own in plots matching plots of lm fits plotted with stat_smooth() even with grouping or facets. This statistic currently supports only lm() fits. By default geom “point” is used to plot the residual from a fitted model.

Add preliminary version of stat_fit_augment(), which uses package ‘broom’ for maximum flexibility in model function choice, to augment the data with additional columns of values derived from a model fit.

Please, report any problems you encounter, and suggest possible changes or additions to the functionality!

NOTE: This version of the package is now available from CRAN.
