Create an empty data.frame

Question

I want a way to create a empty data.frame in R, I just want to point out data types for each column and name it without any row created. df <- data.frame(Date=as.Date("29/05/2019", format="%d/%m/%Y"), File="", User="", stringsAsFactors=FALSE) df <- df[-1,] currently I am using this command, which is doing my work but also creating a row which is waste to me. Suggest me a more efficient way to do it. Select the correct answer from above options

Answer 1

To create a data frame with empty rows, just initialize it with empty vectors as follows: dataframe <- data.frame(Date=as.Date(character()), File=character(), User=character(), stringsAsFactors=FALSE) str(dataframe) Output: 'data.frame': 0 obs. of 3 variables: $ Date: 'Date' num(0) $ File: chr $ User: chr If you want to learn more about R programming watch this tutorial on Introduction to Data Science with R
