# Convert list of lists to dataframe in R

• Last Updated : 30 May, 2021

In this article, we will discuss how to convert a list of lists to dataframe in R Programming Language. We will convert a list of lists to a data frame both by row and by column.

Example 1: R program to create three lists inside a list with numeric and character type and convert into dataframe by column.

Syntax as.data.frame(do.call(cbind, list_name))

Parameters: Where cbind is to convert list to dataframe by column and list_name is the input list which is list  of lists

Code:

## R

 `# create list and create 3 lists ``# inside this list``lists = ``list``(list1 = ``list``(1, 2, 3, 4, 5),``             ``list2 = ``list``(``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``),``             ``list3 = ``list``(2, 3, 4, 5, 6))`` ` `# convert list of lists into dataframe``# by column``print``(``as.data.frame``(``do.call``(cbind, lists)))`

Output:

```  list1 list2 list3
1     1     a     2
2     2     b     3
3     3     c     4
4     4     d     5
5     5     e     6```

Example 2: R program to create two lists inside a list with numeric and character type and convert into dataframe by column

## R

 `# create list and create 2 lists ``# inside this list``lists = ``list``(list1 = ``list``(1, 2, 3, 4, 5),``             ``list2 = ``list``(``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``))`` ` `# convert list of lists into``# dataframe by column``print``(``as.data.frame``(``do.call``(cbind, lists)))`

Output:

```  list1 list2
1     1     a
2     2     b
3     3     c
4     4     d
5     5     e```

Example 3: R program to create three lists inside a list with numeric and character type and convert into dataframe by column.

Syntax: as.data.frame(do.call(rbind,list_name))

Parameters: Where rbind is to convert list to dataframe by row and list_name is the input list which is list  of lists

## R

 `# create list and create 3 lists ``# inside this list``lists = ``list``(list1 = ``list``(1, 2, 3, 4, 5),``             ``list2 = ``list``(``'a'``, ``'b'``, ``'c'``, ``'d'``, ``'e'``),``             ``list3 = ``list``(2, 3, 4, 5, 6))`` ` `# convert list of lists into dataframe ``# by row``print``(``as.data.frame``(``do.call``(rbind, lists)))`

Output:

```      V1 V2 V3 V4 V5
list1  1  2  3  4  5
list2  a  b  c  d  e
list3  2  3  4  5  6```
