nulls_to_nas: Functions for dealing with NULL elements of a list
In twolodzko/lolplyr: Adapting dplyr for lists-of-lists

Description Usage Arguments Examples

Convert all the NULL elements of list to NAs using nulls_to_nas. The unlist_with_nas function is an equivalent of unlist that replaces all the NULL entries with NA's instead of dropping them. Function drop_nulls non-recursively removes the NULL entries of a list.

nulls_to_nas(x, null = NA)

unlist_with_nas(x, null = NA)

drop_nulls(x)

`x`	a list.
`null`	the replacement value for `NULL` elements.

lst <- list(1, 2, NULL, 3, 4:6, list(NULL, 7, 8), as.list(9:11))
names(lst) <- letters[seq_along(lst)]

nulls_to_nas(lst)
unlist_with_nas(lst)
drop_nulls(lst)
