z22_pivot_longer: Cast feature grid to a long table

In z22: Official Gridded Data from the German Census 2022

Cast feature grid to a long table

Description

Helper function to convert the output of z22_data to a long table. This can be useful for plotting or other data wrangling tasks.

Note that pivoting can quickly become expensive for larger 100m grids.

Usage

z22_pivot_longer(.data, feature, lang = c("english", "german"))

Arguments

.data	Output of z22_data.
feature	A grid feature that is represented by .data.
lang	Specifies the language of the output description. Can be either "english" (default) or "german". Note that the English descriptions are only ad-hoc translations based off the German originals.

Details

Note that all columns starting with "cat_*" are automatically used for pivoting.

Value

A dataframe containing the columns category, value, x and y. All non-category columns are preserved.

Examples

# get feature grid
age <- z22_data("age_short", res = "10km")

# pivot to a long table
z22_pivot_longer(age, feature = "age_short")
