Create empty dataframe in R with same columns

Question

 names(U1)  [1] "username"     "review_count" "forum_posts"  "age"          "avg_interval" [6] "avg_sim"      "class" 

So how do I create an empty data frame U1.RN that will have same columns as U1?

Answer 1

You can do this:

U1.RN <- U1[0,] 

Answer 2

Along the lines of df[0,] you can also use a boolean mask which might make the code more readable:

 df[FALSE,]
