R: how to access a tibble in a tibble?

Question

I am reading Hadley\'s: http://r4ds.had.co.nz/tibbles.html

However, I am still having difficulty referencing a tibble in a tibble.

From tidyquant's documentation, using tq_get(symbol, get = "key.ratios") returns a nested tibble. Inside the tibble's "data" column are other tables with columns: section, sub.section, group, category, and date.

You were originally trying to access a column called "Financials" in the main data frame, but no such column exists (it has only "section" and "data"). "Financials" is, instead, an element (row) of the "section" column. I think instead you want:

filter(f, section == "Financials") %>% unnest()
