Multidimensional coordinate mappings

Allow stat layers to receive a sequence of positional variables rather than only x and y.

Usage

aes_coord(.data, prefix)

get_aes_coord(data)

aes_c(...)

Arguments

.data, data

A data frame. .data stands in for the data passed to ggplot2::ggplot(), while data is expected to have been pre-processed before being passed to a Stat*$compute_*() function.

prefix

A regular expression used to identify the coordinate columns of .data.

...

objects to be concatenated. All NULL entries are dropped before method dispatch unless at the very beginning of the argument list.

Value

A list with class uneval. Components of the list are either quosures or constants.

Details

These functions coordinate (pun intended) the use of more than two positional variables in plot layers. Pass multidimensional coordinates to a stat via mapping = aes_coord(...) and reconcile the recovered coordinates with x and y (which are overridden if present) in Stat*$compute_*(); see the StatChull source code for an example. Use aes_c() to concatenate aesthetic mappings.
