One simple approach to creating an empty DataFrame in the R programming language is by using data. frame() method without any params. This creates an R DataFrame without rows and columns (0 rows and 0 columns).
To create an empty Data Frame in R, call data. frame() function, and pas no arguments to it. The function returns an empty Data Frame with zero rows and zero columns.
How to Create a Data Frame. We can create a dataframe in R by passing the variable a,b,c,d into the data. frame() function. We can R create dataframe and name the columns with name() and simply specify the name of the variables.
You can do this:
U1.RN <- U1[0,] Along the lines of df[0,] you can also use a boolean mask which might make the code more readable:
df[FALSE,] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
