Change expect_equal() to include a tolerance, to satisfy CRAN testing.
Delete note about old (before 2.2.1) versions of ggplot2, thanks to @olivroy for pull request 246.
Add website link to DESCRIPTION, thanks to @olivroy for pull request 241.
Add min.segment.length to the options table in the examples page, thanks to @jwhendy for mentioning this.
Add example for how to use ggrepel with sf objects, i.e. geom_text_repel(..., stat = "sf_coordinates"), thanks to @francisbarton for pull request 236.
Use expect_equal(x, y) instead of expect_true(identical(x, y)), see issue 242 for details.
ggrepel::geom_text_repel(seed = 1), this will no longer override the seed for other unrelated code. Thanks to @kassambara for reporting this in issue 228.v[i] = {0,0} that arise for some versions of the clang compiler. Thanks to @Krascal and @vrognas for reporting this in issue 184.warning: use of bitwise '&' with boolean operandsChange internal column names, so that ggrepel::position_nudge_repel() can now be used with ggplot2::geom_text(). This should also allow us to use new nudge functions from the ggpp package by @aphalo. Thanks to @aphalo for pull request 193.
Improve handling of justification for angle different from zero in ggrepel::geom_text_repel() pull request 196.
geom_label_repel()). The same plot would look OK with ggrepel 0.8.2, but incorrect with ggrepel 0.9.0. Thanks to Ben Baumer (@beanumber) for reporting this in issue 182.max.overlaps stops ggrepel from trying to label overcrowded data points. The default setting is max.overlaps = 10, so text labels that overlap more than 10 things (points or labels) will be excluded from further calculations and rendering. Of course, we can set max.overlaps = Inf to restore the behavior in ggrepel 0.8.1. See [issue 48] for more discussion. We can also use option(ggrepel.max.overlaps = Inf) to disable this new functionality and display all labels, regardless of too many overlaps.Add examples to the vignette for ggplot2::position_jitter() and ggbeeswarm::position_quasirandom()
Line segments can now be curved (#131, @malcolmbarrett). Add examples to the vignette showing different options.
Add max.time option to limit the number of seconds spent trying to position the text labels.
Add verbose option to show timing information: seconds elapse, iteration count, number of remaining overlaps (thanks to @MichaelChirico #159).
Add bg.color and bg.r aesthetics for geom_text() to display shadows behind text labels. Thanks to @rcannood for adding this feature with pull request 142.
Line segments are the same color as the text by default (#164, @lishinkou).
Text justification for multi-line text labels should be working as expected. Thanks to @johnhenrypezzuto and @phalteman for comments in issue 137.
is.unit(x) instead of class(x) == "unit" in issue 141. This should future-proof ggrepel for new versions of the grid package.xlim = c(-Inf, Inf) is treated. Thanks to @thomasp85 for pointing out the bug in issue 136.geom_label_repel(..., point.padding=NA). Reported by @mlell in issue 104.Add support for position parameter. See issue 69. This allows us to add text labels to points positioned with position_jitter(), position_dodge(), position_jitterdodge(), etc.
Please note that this feature will not work with ggplot2 2.2.1 or older.
Thanks to @AliciaSchep and @aphalo
Fix warning about hjust. See issue 93.
Fix bug when subset of points is labeled in geom_label_repel. See issue 92.
Thanks to @AliciaSchep
Add support for hjust and vjust parameters. See issue 69. Also see new examples in the vignette.
Add code to avoid intersecting line segments. See issue 34.
Fix intersection between lines and rectangles, to reproduce the same aesthetically pleasant behavior as in version 0.6.5.
This is an improvement on the sloppy implementation introduced in 0.6.8. See commit 28633d for more information.
Reproduce identical plots by using seed = 1 to set the seed in geom_text_repel() or geom_label_repel(). By default, no seed will be set.
This is an improvement on the sloppy implementation introduced in 0.6.2. See issue 33 and issue 73 for more discussion of this feature. Thanks to Pierre Gramme for reminding me about this via email.
Thanks to @seaaan
unit() instead of only units. See issue 79.Thanks to @zkamvar
xlim or ylim. See pull 74.facet_wrap or facet_grid that have no labeled points. Thanks to @pcroteau for pull 70.direction in geom_text_repel() and geom_label_repel(). Thanks to @AliciaSchep for pull 68.xlim and ylim in geom_text_repel() and geom_label_repel(). Thanks to @lukauskas for pull 67.parse = TRUE in geom_text_repel() and geom_label_repel(). Thanks to @fawda123 for issue 60.Thanks to @jiho for these:
changed alpha in geom_label_repel() to control text, label background, label border, and segment.
Allow segment.colour as well as segment.color.
By default, map text color and text alpha to the segment color unless they are overridden.
Call scales::alpha() instead of alpha().
coord_polar(). See issue 56.point.padding=NA to ignore data points in repulsion calculations.Stop the labels from escaping the plot boundaries instead of applying a force at the boundary.
Call set.seed within geom_text_repel() and geom_label_repel() to allow recreating identical plots. Thanks to @erikor for issue 33.
min.segment.length to geom_text_repel() and geom_label_repel().repel_boxes.cpp. Dampen forces to tune how the labels move. The result looks better, at least for the examples in the vignette.Add segment.alpha as an option for geom_text_repel() and geom_label_repel().
Implement angle aesthetic for geom_text_repel(), the same way as done in ggplot2 geom_text().
Move nudge_x and nudge_y out of the aesthetics function aes(). This makes ggrepel consistent with ggplot2 functions geom_text() and geom_label(). Backwards incompatible with 0.5.1.
Restore segment.color as an option for geom_text_repel() and geom_label_repel().
Tweak repel_boxes.cpp. Do not weight repulsion force by ratios of bounding box heights and widths. This seems to perform better, especially after rotating text labels.
rnorm().point.padding so that users can configure how far labels are pushed away from data points.Optimize C++ code for a 2.5X speed improvment.
Delete unnecessary .Rd files.
FIXES
geom_label_repel(). Now there is no gap between the end of the segment and the label border.FIXES
spring_force() so that it never returns NaN.nudge_x and nudge_y to better control positioning of labels.Add arrow parameter to allow plotting arrows that point to the labeled data points rather than plain line segments.
Always draw segments, even if the labeled point is very close to the label.
FIXES
Fix point.padding so that horizontal and vertical padding is calculated correctly.
Tweak forces to improve layout near borders and in crowded areas.
Add new parameter point.padding to add padding around the labeled points. The line segment will stop before reaching the coordinates of the point. The text labels are also now padded from the line segment to improve legibility.
Add volcano plot to the vignette usage examples.
Add Travis continuous integration to test against R-devel, R-release, and R-oldrel.
Dampen repulsion force to slightly improve algorithm efficiency.
Move intersect_line_rectangle() to src/repel_boxes.cpp.
Remove unused imports: colorspace.
Update NAMESPACE with new version of roxygen.
Use spring force to attract each label to its own point.
Change default maximum iterations from 10,000 to 2000.
Update man pages.
Remove unused code.
Update geom_text_repel() and geom_label_repel().
Change label.padding to box.padding.
Remove unused imports.
Add geom_label_repel().
Add fudge width to help with legends.
Add expand=TRUE to allow text to be placed in the expanded plot area.
Add man/ folder.
Add links to ggplot2 docs in vignette.
Add unused R implementation of repel_boxes(), just for your reference.
