find_parents: Find larger grouping areas (parents) of a smaller brain area...
In valeriabonapersona/abc4d: Analysis of Brain Cells in 4 Dimensions

The Allen Brain Atlas is organized with a tree structure, where smaller brain areas (e.g. nuclei) are grouped into larger brain areas. This function allows you to find the parent of a sub-brain area of choice. Returns only one level up in the tree structure.

1	find_parents(atlas, child)

`atlas`	Data frame with (at least) two character variables: one for the parents (parent_acronym), and one for the children (acronym).
`child`	Acronym of the child brain area. It must be a character vector of length 1.

#' x <- data.frame(
parent_acronym = c(rep("main_parent", 3), rep("child_with_children", 2), "grandchild_with_children"),
acronym = c("main_parent", "child_with_children", "child_without_children", "grandchild_with_children", "grandchild_without_children", "great_grandchild"))
this_child <- "child_with_children"

find_parents(atlas = x, child = this_child)
