directlabels 2024.4.16

• fix make.tiebreaker issue with constant data.

directlabels 2024.1.21 (2024-01-24)

• fix legends2hide issue with ggplot2 3.5.0.

directlabels 2023.8.25 (2023-09-01)

• CRAN NOTE doc fixes.
• use Suggests conditionally in examples/tests.

directlabels 2021.2.24

• rgb to grayscale formula corrected in polygon.method().

directlabels 2021.1.13 (2021-01-16)

• Remove bitmapType cairo in examples vignette.

directlabels 2020.12.29 (2021-01-05)

• fix for single ggplot with two geom_dl with same method. previously this would create two grobs with the same name in a single gTree, which is not allowed (as documented in ?gTree) and resulted in only the first geom_dl being drawn. Now we append a unique integer id to each name so that grid draws both geom_dl.
• fix for lattice: Get lattice transformation functions working again + tests. (Error: data must have a column named label for qqmath examples)
• dldoc no longer uses type="cairo" at request of CRAN.

directlabels 2020.6.30

• custom.colors argument for polygon.method, default choice of white or black depending on how dark the color would be if rendered as grayscale.

directlabels 2020.6.17 (2020-06-25)

• grid grobs have names.
• vignette example / LOPART100 data for black/blue pos swapped for t=100. (bug fix in make.tiebreaker, use rule=2 in approx for no NA)
• using top.qp with one point gave an error: need at least two non-NA values to interpolate. (bug fix in make.tiebreaker, only run approx if there are at least two values)
• legends2hide inside tryCatch to fix error with parsing legends in ggplots with custom themes, https://github.com/tdhock/directlabels/issues/6
• fix test failures that showed up with new code.
• examples vignette for geom_dl with same aes(label), but different aes(label.group, color).
• draw.polygons/polygon.method support top/bottom as well as first/last/left/right. New *.polygons methods.

directlabels 2020.6.7

• initial code for:
• polygons below the point.
• aes(label) which may have the same value for two different aes(group) values, e.g. two algorithms/groups which both compute the same thing, optimal changepoint tau^*, but we want to compute and show a label for each of them.
• using stringDescent to compute height of boxes. maybe consider grobDescent or descentDetails?

directlabels 2020.1.31 (2020-02-01)

• remove Suggest ElemStatLearn.
• remove prostate dl.combine example.

directlabels 2019.12.5

• update for new testing software.

directlabels 2018.10.5

• Non-syntactic variable names supported, e.g. aes(color='car class')

directlabels 2018.5.22

• Update Suggest dplyr to pass CRAN checks.

directlabels 2017.03.31 (2017-04-08)

• test case and bugfix for lasso.labels with a constant line.

directlabels 2017.03.24

• test case and bugfix for using directlabels when ggplot2 is not attached to the global namespace. this happens if directlabels is used in a ggplot in a package that imports ggplot2 but does not attach it, e.g. https://github.com/tdhock/penaltyLearning/blob/master/R/IntervalRegression.R

directlabels 2017.01.03

• Test and bugfix for angled.boxes -- there was some problem with the colour column (one of the columns to.restore after applying far.from.others.borders) being treated as a factor.

directlabels 2016.10.25

• delete browser() in qp.labels

directlabels 2015.12.16 (2015-12-18)

• importFrom non-base packages.

directlabels 2015.12.15

• ggplot2 does not need to be installed for package checks to pass.

directlabels 2015.12.14

• suggest ggplot2 >= 2.0.

directlabels 2015.11.28

• Works with new ggplot2 >= 1.0.1.9003 internals. (and no longer works with older ggplot2 internals!)

directlabels 2015.6.17

• Namespaces fixes to ensure that R CMD check runs cleanly, and that you can use 'geom_dl()' without attaching directlabels to the search path.

directlabels 2014.6.13

• geom_dl(show_guide=FALSE) is default.

directlabels 2014.5.12

• custom colors for dotplots in lattice, see etc/lattice-custom-colors.R

directlabels 2014.4.25

• BUGFIX: bumpup works when there is only 1 group.

directlabels 2014.1.31

• use fill if no colour in ggplots.
• guides(others_with_colour="none")

directlabels 2014.1.27

• polygon.methods for lineplots.

directlabels 2013.11.21

• projectionSeconds data set and angled.boxes Positioning Method, inspired by Mark Schmidt's prettyPlot. http://www.di.ens.fr/~mschmidt/Software/prettyPlot.html
• draw.rects draws a rotated box when rot is specified.

directlabels 2013.9.17

• label.endpoints can handle the case (common for scatterplots) where there are several endpoints with the same x value.

directlabels 2013.8.2

• geom_dl aes inherits from the colored geom aes.

directlabels 2013.7.24

• Doc updates: drawDetails.dlgrob documents interpretation of columns, apply.method uses itemize list, \code{\link{fun}} hyperlinks.

directlabels 2013.6.15 (2013-07-23)

• Documentation updates.

directlabels 2013.6.14

• Depend on quadprog.
• Bugfix for reduce.cex.lr: decrease the text size based on previous cex, rather than assuming the previous cex is 1.
• Remove follow.points, perpendicular.(lines|grid).
• Change with/within/transform/subset to alternatives that do not generate NOTEs during package check.
