I have data frame of data frames from
purrr and want to write each nested data frame to a CSV.
> df # A tibble: 3 × 2 dataset data <chr> <list> 1 aab <tibble [681 × 60]> 2 aae <tibble [1,486 × 173]> 3 acm <tibble [3,496 × 139]>
That is, I want 3 CSVs from above: one CSV for each tibble under "data".
I prefer tidyverse functions to
lapply or similar.
I think it's gotta be something using
map() or similar function:
df %>% map(~write_csv(data, file=[how to get filename from 'dataset' column?))
If you use
purrr::by_row, you can access the
temp <- df %>% by_row(~write.csv(.$data, file = .$dataset))
This will save each tibble in a row to a separate file under the name of dataset.
