Wait, that would simplify the return value into a matrix when there are
no NULLs. But lapply(mylist2, `[[`, 'b') should work in both cases,
which in my opinion goes to show the dangers of using simplifying
function

Hallo all
I found a strange problem for coding if part of list is NULL.
In this case, sapply result is ***list of data frames*** but if there is no
NULL leaf, the result is ***list of vectors***.
I tried simplify option but it did not help me neither I found anything in
help page.
