This function creates a nested sdc hierarchy from various input structures.

hier_import(inp, from = "json", root = NULL)

Arguments

inp	an object that should be imported. Argument from specifies the input format.
from	(character) from which format should be imported. Possible choices are: "json": a json-encoded string as created using hier_convert() with argument as = "json") "df": a data.frame in @;level-format or an input created with hier_convert() with argument as = "df") "dt": a data.frame in @;level-format or an input created with hier_convert() with argument as = "dt") "argus": a json-encoded string as created using hier_convert() with argument as = "argus") "code": a json-encoded string as created using hier_convert() with argument as = "code") "hrc": text-files in tau-argus hrc-format "sdc": a json-encoded string as created using hier_convert() with argument as = "sdc")
root	optional name of overall total

Value

a (nested) hierarchy

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)
#> Total
#> ├─A
#> │ ├─a1
#> │ └─a2
#> └─B
#>   ├─b1
#>   │ └─b1a
#>   └─b2

df <- hier_convert(h, as = "df")
hier_display(df)
#> Total
#> ├─A
#> │ ├─a1
#> │ └─a2
#> └─B
#>   ├─b1
#>   │ └─b1a
