spinifex (version 0.3.2)

proto_text: Tour proto for data, text labels

Description

Adds geom_text() of the projected data.

Usage

proto_text(
  aes_args = list(),
  identity_args = list(nudge_x = 0.05),
  row_index = TRUE
)

Arguments

aes_args

A list of arguments to call inside of aes(). aesthetic mapping of the primary geom. For example, geom_point(aes(color = my_fct, shape = my_fct)) becomes aes_args = list(color = my_fct, shape = my_fct).

identity_args

A list of static, identity arguments passed into the primary geom. For instance, geom_point(size = 2, alpha = .7) becomes identity_args = list(size = 2, alpha = .7). Also passes more foundational arguments such as stat and position, though these have been tested less.

row_index

A numeric or logical index of rows to subset to. Defaults to NULL, all observations.
