convert_relative_initial(data, col = "atoutput")

Arguments

data	Dataframe to apply the transformation to.
col	Character value giving the name of the column to transform. Default is `"atoutput"`.

Value

Dataframe with transformed column 'col'.

Examples

df <- convert_relative_initial(ref_structn)
head(df[df$layer == 1, ], n = 15)
