Weight shares within a frame — scale

Normalised weights, either of the whole object or within each parent group.

scale_share(x, frame, weight = NULL, within = NULL)

Arguments

x: A NestedScale.
frame: Frame to report shares for.
weight: Weight column. NULL uses the default.
within: Optional coarser frame to normalise within. NULL normalises over the whole object.

Value

A data.frame with a code column named frame, the weight, and share. When within is given, a column of that name carries the parent code.

Examples

s <- scale_example()
scale_share(s, "class", weight = "size")
#>   class size     share
#> 1    G1  300 0.1428571
#> 2    G2  700 0.3333333
#> 3    S1 1100 0.5238095
scale_share(s, "class", weight = "size", within = "sector")
#>   class sector size share
#> 1    G1      P  300   0.3
#> 2    G2      P  700   0.7
#> 3    S1      S 1100   1.0
