sdcHierarchies (version 0.22.0)

hier_convert: Converts hierarchies into different formats

Description

This functions allows to convert nested hierarchies into other data structures.

Usage

hier_convert(tree, as = "df")

Arguments

tree

a (nested) hierarchy created using hier_create() or modified using hier_add(), hier_delete() or hier_rename().

as

(character) specifying the export format. Possible choices are:

• "df": a data.frame with two columns. The first columns contains a string containing as many @ as the level of the node in the string (e.g @ corresponds to the overall total while @ would be all codes contributing to the total. The second column contains the names of the levels.

• "dt": like the df-version but this result is converted to a data.table

• "argus": used to create hrc-files suitable for tau-argus

• "json": json format suitable e.g. as input for the shinyTree package.

• "code": code required to generate the hierarchy

• "sdc": a list which is a suitable input for sdcTable

Examples

h <- hier_create(root = "Total", nodes = LETTERS[1:2])
h <- hier_add(h, root = "A", nodes = c("a1", "a2"))
h <- hier_add(h, root = "B", nodes = c("b1", "b2"))
h <- hier_add(h, root = "b1", nodes = "b1a")
hier_display(h)

# required code to build the hierarchy
hier_convert(h, as = "code")

# data.frame
hier_convert(h, as = "df")
