2.1 Data frames

1. Create a data frame with three observations of two variables. Name the variables x1 and x2. Make up numbers for the values of the observed variables.

   library(tidyverse)

   my_data <-
     tibble(
       x1 = c(1, 2, 3),
       x2 = c("c", "b", "a")
     )

2. Using any of the functions/methods from the discourse, display the number of observations and variables of the data frame.

   glimpse(my_data)

   Observations: 3
   Variables: 2
   $ x1 <dbl> 1, 2, 3
   $ x2 <chr> "c", "b", "a"

   Or

   head(my_data)

   # A tibble: 3 x 2
        x1 x2   
     <dbl> <chr>
   1     1 c    
   2     2 b    
   3     3 a
