Keeping only data.frames in list of list

Question

My list looks something like that and I would like to remove those type=character so that I can use rbindlist.

I tried the following, but is_df became empty 'List of 0'.

is_df <- sapply(lst2, is.data.frame)

finaldf <- do.call("rbind.fill", lst2[is_df])

Answer 1

We can use keep with bind_rows

library(purrr)
library(dplyr)
keep(lst2, is.data.frame) %>% 
      bind_rows
