Calculate Trendecon Main Indices for Switzerland

Source: R/proc_trendecon_ch.R

Updates every Swiss index from Google Trends and copies the seasonally adjusted series into data/ch. Indices are processed independently, so a failure in one does not prevent the others from updating. See proc_trendecon() for details.

proc_trendecon_ch(backfill_from = NULL)

Arguments

backfill_from

Optional start date (YYYY-mm-dd). If supplied, each keyword's daily series is backfilled from this date before the regular update, to repair a gap left by an outage. Use once, then omit.

Value

Invisibly, a per-index status data frame.
