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. 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 ipay top holdings
