Check if an object is a list of lists
is_list_of_lists(object)is_list_of_lists(object)
object |
any R object (anything) |
TRUE if object is a list of lists, FALSE if it is not. Any non-list elements will cause this function to return FALSE
Other nested_lists:
list_of_lists_retrieve_second_level_property()
Retrieve element from sublist of nested list
list_of_lists_retrieve_second_level_property( list_of_lists, name_of_property, function_for_sublist_assertion = function(x) { return(TRUE) } )list_of_lists_retrieve_second_level_property( list_of_lists, name_of_property, function_for_sublist_assertion = function(x) { return(TRUE) } )
list_of_lists |
A list containing at least one sublist lists (list) |
name_of_property |
The name of the property to retrieve. For example if your sublists have some element named 'petal_length', you could use name_of_property == petal_lengt h (string) |
function_for_sublist_assertion |
Some function that takes one argument (teach sublist) and returns TRUE/FALSE. Function is fed into an assertion. By default, no assertion is applied (function). This property is useful if you want to check all sublists are of a certain class. |
Will error if list is zero_length
vector of the same length as the input list (vector)
