Typo in value of `pi` in Figure 20.2

[gvelasq]

Happy Pi Day! There's a small typo in the top left of Figure 20.2 where the third element of list a is meant to show pi rounded to 6 decimals. The current value shown in the figure is 3.141525 and the correct value should be 3.141593 as per the reprex below.

a <- list(a = 1:3, b = "a string", c = pi, d = list(-1, -5))

purrr::walk(a, ~ print(.x))
#> [1] 1 2 3
#> [1] "a string"
#> [1] 3.141593
#> [[1]]
#> [1] -1
#> 
#> [[2]]
#> [1] -5
