WebA subset is a smaller set of outcomes that is contained in that larger set. So if you are rolling a die and what to know the probability of getting an odd number, you are looking at the subset that contains all the outcomes in which the die comes up with an odd number (1, 3, and 5).

To be retained, the row must produce a value of TRUE for all conditions. Note that when a condition evaluates to NA the row will be dropped, unlike base subsetting with [. Usage WebIf something belongs to set then it means thats it is an element of that set as a whole but if a set is a subset of another set then it means all the elements of that set belong to the set to which that set is a subset. Ex: Lets take two sets A = { 1, 2, 3 } & B = { x ∣ x is a natural number and x < 5 } trek and trail
