Fetch DWD crowd reports

Fetch DWD crowd reports

Usage

dwd_crowd_reports(
  safe = TRUE,
  refresh = FALSE,
  flatten = FALSE,
  flatten_mode = "json"
)

Arguments

safe

Logical; if TRUE (default), apply rate-limiting and cache GET responses to tools::R_user_dir("bunddev", "cache").

refresh

Logical; if TRUE, ignore cached responses and re-fetch from the API (default FALSE).

flatten

Logical; if TRUE, simplify nested list columns according to flatten_mode. Default FALSE keeps list columns as-is.

flatten_mode

How to handle list columns when flatten = TRUE:

"drop"

Remove list columns entirely. Use when nested data is not needed.

"json"

Convert each list element to a JSON string. Preserves all data in a text-queryable format. This is the default.

"unnest"

Expand list columns into multiple rows via tidyr::unnest_longer(). Warning: this can significantly increase the number of rows.
