Fixed dice not rendering with ggplot2 >= 4.0
— The drawDetails.DiceGrob S3 method was not registered in
the package NAMESPACE, so grid never dispatched to the custom drawing
code. Neither tiles nor pips were drawn. Fixed by adding
S3method(grid::drawDetails, DiceGrob) to NAMESPACE via
@exportS3Method.
Fixed invisible pips when fill is not
mapped — When the fill aesthetic was not mapped
(default NA), pip colour was also set to
NA, making pips invisible. Pips now default to black when
fill is unmapped.
pip_scale parameter — New argument
to geom_dice() that controls pip diameter as a fraction
(0–1) of the maximum available space inside each die face. When
size is constant (not mapped), all pips are drawn at
pip_scale × max_diameter. When size is mapped
to a variable, pips scale between 25% and pip_scale of the
maximum pip diameter. Set pip_scale = NULL to disable
auto-scaling and use the raw size aesthetic (legacy
behaviour). Default: 0.75.
Deferred rendering via DiceGrob —
Pip sizing is now calculated at grid draw time rather than ggplot build
time, so pip diameters adapt correctly to the final figure
dimensions.
Scale expansion for edge tiles —
setup_data now exposes
xmin/xmax/ymin/ymax
so ggplot2 trains axis scales to include the full tile area, preventing
clipping of border tiles.
New datasets — sample_dice_large
(480 rows, 60 taxa) and sample_dice_miRNA (~90 rows, miRNA
dysregulation) are included for demonstrating high-density and
categorical-fill use cases.
Default pip sizing changed — Pips are now
auto-scaled to fill the die face via the new pip_scale
parameter (default 0.75). In v1.0.0 pips used the raw
size aesthetic (default 3), which often left
excessive whitespace or caused pips to overflow tile borders at certain
figure sizes. Migration: add
pip_scale = NULL to your geom_dice() call to
restore the exact v1.0.0 appearance.
Legend key for unmapped fill — When
fill is not mapped, legend keys now draw a solid black dot
instead of an empty circle, improving readability. This is a cosmetic
change with no opt-out.
Axis scale expansion — Edge tiles are no longer
clipped because setup_data now reports tile extents to
ggplot2. Plots may show slightly more padding around the border compared
to v1.0.0.
draw_panel signature changed — The
method now takes explicit named arguments (na.rm,
ndots, x_length, y_length,
pip_scale) instead of params, .... Code that
subclassed GeomDice or called draw_panel
directly will need updating.Sample datasets restructured:
sample_dice_data1: 48 rows → 160 rows (8 taxa × 4
diseases × 5 specimens). Columns are the same but lfc and
q may now contain NA.sample_dice_data2: 48 rows → 160 rows; the
replicate column has been removed. Column count changed
from 6 to 5. Scripts that reference
sample_dice_data2$replicate or hard-code row counts from
either dataset will break.tibble is now a hard dependency —
added to Imports for column_to_rownames() /
remove_rownames().
Minimum R version raised to 4.1.0 (was 4.0.0). R
4.1 is required for the native pipe operator (|>) used
internally.
