Hi, please help me solve two simple questions related to R, based on the document attached below.
1. How can you tell if an object is a tibble?
2. The following code defines a data frame: df <- data.frame(x= 1, y =
"a")
Try the following code and see the outputs: df$x, df[, ‘y’]
Now change df to a tibble: new_df<-as_tibble(df)
How to realize df$x, df[, ‘y’] for new_df using pipe?
