In an earlier quiz you created a vector v3 of length 8. Compare each value in that vector to see if it is greater than 5 (you should end up with a vector of TRUE and FALSE).
v3 > 5
Extract a subset of the vector v3 that includes only the values greater than 5
v3[v3 > 5]
Compare each value in the "Petal.Length" of the (built-in) "iris" dataset to see which are greater than 5
iris$Petal.Length > 5
Extract the subset of rows from iris where Petal.Length is greater than 5
iris[iris$Petal.Length > 5, ]
Extract the subset of rows from iris where Petal.Length is greater than 5 and the Species is "versicolor"
iris[iris$Petal.Length > 5 & iris$Species == "versicolor", ]
