forestploter 1.2.0

Breaking changes

• sizes is now a multiple of one line of text for both points and summary diamonds, where it used to be char for one and a fraction of the row height for the other. Summary diamonds are flatter than in 1.1.4; pass a larger sizes to restore the old look.
• Point size now follows the theme’s base_size instead of the pointsize of whichever device happened to be open. Unchanged at the default base_size.
• Summary rows in grouped plots grow to the height the group offsets need, rather than always doubling.

New features

• The plot is now built step by step with the pipe |>. forest() draws the table and the confidence intervals, and the rest is added with set_xaxis() (limits, tick marks, scale and vertical lines), set_labs() (title, x-axis labels, footnote, arrow labels and legend text), scale_sizes() (point sizes from study weights) and set_style(). They must be used before the plot is edited with edit_plot() and the other editing functions.
• Graphical parameters are set with forest_style(), which takes one gpar() for each part of the plot and is given to the new style argument of forest(). forest_theme() is superseded but keeps working, also with set_style(); ?forest_theme shows how its arguments map onto forest_style().
• New fit of forest_style() lets the plot use the space it is drawn in: "width" gives the free width to the CI columns and "both" also shares the free height between the rows. The default "none" keeps the natural size of the plot, as before. The autofit argument of print() will be deprecated in favour of it.
• New scale_sizes() to scale study weights into point sizes, following metafor and meta. Without it, sizes are used as they are (#37).
• A warning is given when the plot is drawn if sizes falls outside 0.1 to 2, or if grouped confidence intervals are likely to overlap given nudge_y.
• In the new functions, an argument left out keeps its current value and NULL goes back to the default. NA is only used for a CI column left at its default, as in xlim = list(c(0, 4), NA).

Superseded

• The arguments of forest() that the functions above replace are still accepted and draw the same plot. Each of them gives a message once per session pointing to its replacement: xlim, ticks_at, ticks_digits, ticks_minor, x_trans and vert_line to set_xaxis(), and arrow_lab, xlab, title and footnote to set_labs(), and theme to style. They will be removed in 2.0.0.
• forest() now gives a message once per session for an argument in ... that neither fn_ci, fn_summary nor index_args takes, instead of dropping it silently. The argument is still ignored.
• The package now requires R >= 4.1.0 for the native pipe used in the examples.

Bug fixes

• Fix automatic ticks_digits dropping decimals on linear axes, which rendered fractional ticks with duplicated labels (e.g. 1, 1.5, 2 as “1”, “2”, “2”).
• Fix error when gp is passed to forest with summary rows.
• Error if the length of est is not a multiple of the length of ci_column, instead of silently dropping the extra series.
• Replace gridtext with gridmicrotex in the vignettes, so the annotation examples are typeset as real LaTeX math.
