In hypercompetent/xstitch: Cross-stitch pattern generation.

Description

Generate array annotation boundary segments for ggplot2

Usage

aba_slice_anno_boundaries(anno, slice_num, plane = "coronal")

Arguments

anno	A 3-d annotation array like that generated by aba_get_annotation_array()
slice_num	A number indicating which slice to use.
plane	Which plane to return. Options are "coronal", "saggital", and "horizontal". Default is "coronal"

Value

a data.frame of segment coordinates with x, xend, y, and yend.

Examples

library(dplyr)
library(ggplot2)

boundary_df <- aba_get_annotation_array() %>%
  aba_symmetrize_matrix("min") %>%
  aba_melt_3d("atlas_id") %>%
  filter(atlas_id != 0) %>%
  aba_slice_anno_boundaries(30, "coronal")

ggplot(boundary_df) +
  geom_segment(aes(x = x, xend = xend,
                   y = y, yend = yend)) +
  scale_y_reverse()
