The Code:
con <- dbConnect(RSQLite::SQLite(), dbname='database.db') # Database connection
currencies <- dbGetQuery(con, "SELECT * FROM currency") # Import currencies
The Error:
Error in result_create(conn@ptr, statement) : no such table: currency
Additionally, you provide some more documentation? Perhaps a list of all of the tables available and variables
? By the way, I'm liking what I'm seeing. Great job with the frequent updates.
Howdy,
The scraper linked is outdated it seems. I got this for the output:

I'm wondering if you have either an updated version or if you could add a table with the format that this project expects the data to be in.
This looks so awesome by the way. Excited to get this working.
