How to create an empty data frame in R?

We can create an empty data frame as follows −

> df <- data.frame(Income=double(),    Age=integer(),    EducationLevel=factor(),    MaritalStatus=logical(),    StateLiving=character(),    stringsAsFactors=FALSE) > str(df) 'data.frame': 0 obs. of 5 variables: $ Income : num $ Age : int $ EducationLevel: Factor w/ 0 levels: $ MaritalStatus : logi $ StateLiving : chr

We can edit this data frame by using −

> edit(df)

This edit command will open a spreadsheet and we can enter the data in the data frame.
