Value

A tbl_data data frame

Examples

## create data frame with two random variables
tbl_data_frame(
  a = rnorm(10),
  b = rnorm(10)
)
#> # A tibble: 10 x 2
#>          a       b
#>      <dbl>   <dbl>
#>  1 -0.206  -0.510 
#>  2  1.09    0.668 
#>  3  0.761  -2.12  
#>  4 -1.41    0.0457

#>  9 -0.523   0.170 
#> 10 -0.604   0.0747

## create variables calculated using previous variables
tbl_data_frame(
  a = rnorm(10),
  b = rnorm(10),
  c = (a + b) / 2,
  d = a + b + c
)
