Web4.2 (Atomic) vectors. A vector is nothing else than a sequence of elements of a certain type. R distinguishes vectors with two different modes.. Atomic vectors: All elements must have the same basic type (e.g., numeric, character, …).; Lists: Special vector mode.Different elements can have different types. Lists are deferred to a later chapter and are not … WebSubsetting in R is easy to learn but hard to master because you need to internalise a number of interrelated concepts: There are six ways to subset atomic vectors. There are three subsetting operators, [[, [, and $. Subsetting operators interact differently with different vector types (e.g., atomic vectors, lists, factors, matrices, and data ...

Almost all data in R is stored in a vector, or even a vector of vectors. A list is a recursive vector: a vector that can contain another vector or list in each of its elements. Lists are one of the most flexible data structures in R.
