Bug fix:
Bug 1
Error: geom_hist_ fails and provides unexpected warnings
Reason: the class name of the discrete variable in ggplot2 is changed from mapped_discrete to ggplot2_mapped_discrete. Therefore, many binary checks by is_mapped_discrete() does not pass.
Bug 2
Error: stat_count_ fails to draw bins
Reason: a default setting of the bin width of the new version ggplot2::stat_count is recently set in set_params; when we replicate set_params of the old version ggplot2, the bin width is not set.
For the radial coordinate, the serial histogram and density are displayed incorrectly (I suppose the engine, ggplot2::coord_polar makes some changes). So, in this version, these features are unavailable for now. Hopefully, we can bring them back in the next release.
Give meaningful content to the size of each non-primitive glyph.
polygon glyph: the default size is 0.5 with unit “cm”. The size of the polygon glyph is the “size” multiplies the polygon coordinates.
serial axes glyph: the default size is 1.5 with unit “cm”.
If it is the “radial” coordinate, the size is the diameter of the enclosing;
If it is the “parallel” coordinate, the size is the width of the enclosing and the aspect ratio of height and width is 1:2.
image glyph: the default size is 1 with unit “cm”. The height of the image is determined by imageheight * size and the width of the image is imagewidth * size.
Export a data fame NBAstats2021 which contains 30 observations and 42 statistics summaries, e.g. team names, points per game, etc.
Fix a bug: for geom_histogram_, the scaling strategy (scale.y and as.mix) is not correct.
The argument name adjust (adjust the proportional maximum height of the estimate, i.e. density, histogram, …) is changed to prop since adjust has already been used in setting the density.
Fix a bug: in this version, all functions can handle data with NAs
For functions geom_hist_ and geom_density2d, if the input x and y are both numerical, neither will be considered as the group variable and a warning will be given.
coord_radar (deprecated) –> coord_radial; also un-export the function coord_polar (reduce the confusion)
Update documentation (fix typos; make it more readable; point out potential risks of coord_serialaxes)
For polygon glyph, if the fill is NA (the fill color is none), it is a poly-line glyph; if the fill is not NA (some real color), it is a polygon glyph. In the old version 0.1.0, the output can only be one type. For example, if fill = c(NA, "red"), then, NA dominates that both glyphs are polylines. In this version, it is more flexible that both polygon and polyline can appear on the same plot with one geom_polygon_glyph call.
