WebR has many data structures. These include atomic vector list matrix data frame factors tables Vectors A vector is the most common and basic data structure in R and is pretty much the workhorse of R. Technically, vectors can be one of two types: atomic vectors lists although the term "vector" most commonly refers to the atomic type not lists. WebThe data types collecting these atomic objects are: Vectors: several elements of a single atomic type (R does not have scalars, they are 1-element vectors) Matrices: collections of equal-length vectors; Factors: categorical data (ordered, unordered) Data frames: a data set, collections of equal-length vectors of different types

WebA vector is a one dimensional array of elements. Vectors are the basic building blocks of R. 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.

WebAtomic vectors are always homogeneous (all elements must be of the same type). Lists may be heterogeneous (the elements can be of different types) as described in the introduction of the vectors chapter. Atomic vectors point to one address in memory, while lists contain a separate reference for each element.
