How to create a List of Dictionaries in R - Step by Step Examples

How to create a List of Dictionaries in R ?

Answer

In R, you can create a list of dictionaries using the `list` function for the outer list and `list` or `named list` function for the inner dictionaries.

✐ Examples

1 Create List of Dictionaries

In this example,

We create two inner dictionaries named dict1 and dict2 using the list function.
We create an outer list named list_of_dicts using the list function and initialize it with the inner dictionaries.
Finally, we print the list of dictionaries to standard output.

R Program

dict1 <- list(key1 = 'value1', key2 = 'value2')
dict2 <- list(key3 = 'value3', key4 = 'value4')
list_of_dicts <- list(dict1, dict2)
print(list_of_dicts)

Output

[[1]]
[[2]]

2 Create List of Dictionaries with Empty Inner Dictionaries

In this example,

We create an empty outer list named list_of_dicts_empty using the list function.
We create two empty inner dictionaries named dict3 and dict4 using the list function.
We use the c function to concatenate the inner dictionaries dict3 and dict4 to the outer list list_of_dicts_empty.
Finally, we print the list of dictionaries with empty inner dictionaries to standard output.

R Program

list_of_dicts_empty <- list()
dict3 <- list()
dict4 <- list()
list_of_dicts_empty <- c(list_of_dicts_empty, list(dict3, dict4))
print(list_of_dicts_empty)

Output

list()
[[1]]
[[2]]
