Create Empty Data Frame with Fixed Number of Rows in R

To create an empty data frame with fixed number of rows but no columns, we can use data.frame function along with the matrix function. That means we need to create a matrix without any column using matrix and save it in a data frame using data.frame function as shown in the below examples.

Example1

Live Demo

> df1<-data.frame(matrix(,nrow=10,ncol=0))
> df1

Output

data frame with 0 columns and 10 rows

Example2

Live Demo

> df2<-data.frame(matrix(,nrow=100,ncol=0))
> df2

Output

data frame with 0 columns and 100 rows

Example3

Live Demo

> df3<-data.frame(matrix(,nrow=39,ncol=0))
> df3

Output

data frame with 0 columns and 39 rows

Example4

Live Demo

> df4<-data.frame(matrix(,nrow=20,ncol=0))
> df4

Output

data frame with 0 columns and 20 rows

Example5

Live Demo

> df5<-data.frame(matrix(,nrow=200,ncol=0))
> df5

Output

data frame with 0 columns and 200 rows

Example6

Live Demo

> df6<-data.frame(matrix(,nrow=150,ncol=0))
> df6

Output

data frame with 0 columns and 150 rows

Example7

Live Demo

> df7<-data.frame(matrix(,nrow=1000,ncol=0))
> df7

Output

data frame with 0 columns and 1000 rows

Example8

Live Demo

> df8<-data.frame(matrix(,nrow=500,ncol=0))
> df8

Output

data frame with 0 columns and 500 rows

Example9

Live Demo

> df9<-data.frame(matrix(,nrow=50000,ncol=0))
> df9

Output

data frame with 0 columns and 50000 rows

Example10

> df10<-data.frame(matrix(,nrow=10000000,ncol=0))
> df10

Output

data frame with 0 columns and 10000000 rows
