Hacer un subset con un data frame consiste en obtener algunas filas o columnas de todo el data frame o algunas que cumplan con una o varias condiciones. Es muy habitual hacer un subset en R con este tipo de estructura para posteriormente analizar los datos.
A is a subset of B (denoted ) and, conversely, B is a superset of A (denoted ). In mathematics, a set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B.

The subset symbol is used in math to describe the relationship between two sets. Typically, the symbol is used in an expression like this: A ⊂ B. In plain language, this expression means that the set A is a subset of the set B. Read more.

What is a subset? A subset, as the name suggests, is a subcollection of any set. Let us assume we have two sets, X and Y. Mathematically speaking, X will be a subset of Y if and only if all the elements of X are present in Y. We can also say that X is contained in Y. This relationship is called inclusion or containment of X in Y.
Set A A is a subset of set B B if every member of set A A is also a member of set B B. Symbolically, this relationship is written as A ⊆ B A ⊆ B . Sets can be related to each other in several different ways: they may not share any members in common, they may share some members in common, or they may share all members in common.
