Plot shapes stacked together

Source: R/p_graphics.R
pile.Rd

Display one or more shapes stacked on the same plot.

Usage

pile(x, ..., .cols = NULL, .ldk_col = NULL)

Arguments

x

A matrix (nx2), list of matrices, or tibble with coo columns.

...

Additional arguments passed to plotting functions.

.cols

Column name(s) to process when x is a tibble. If NULL, automatically detects columns containing coo objects.

.ldk_col

Character. Name of landmark column. If NULL, uses colname_ldk.

Value

Invisibly returns x (for piping).

Details

Stacks all shapes on a single plot. Works with:

  • Single matrix: plots that shape

  • List of matrices: plots all shapes overlaid

  • Tibble: plots all shapes from coo column (or specified .cols)

If a tibble has a landmark column (e.g., coo_ldk), landmarks will be drawn in addition to outlines. Otherwise, falls back to heuristic: if shapes have fewer than 32 points, draws as landmarks; otherwise draws as outlines.

Examples

pile(shapes$cat)

pile(shapes)

pile(bot)

pile(bot, .cols = "coo")
