Lists • One-Dimensional • Heterogeneousdata structure • Indexing Starts from ‘1’. • List can be a list of vectors, a list of matrices, a list of characters,a factor. a list of functions, etc. A List may contain another list as its item
Arrays • fixed numberof dimensions • allocation of space at contiguous memory locations • Unidimensional arrays are called vectors • Two-dimensional arrays are called matrices • Arrays are N-Dimensional data sets. Syntax – Define an R Array • variable <- array(list, dimension) • where list contains the elements of array and dimension is a list containing the information about dimensionality of the array. • If dimension is c(2,5,4,8), the array is 4-Dimensional with dimensions 2x5x4x8.

R Factors The commandused to create or modify a factor in R language is – is a vector along with the distinct values of vector as levels. Factors are useful during statistical modelling. factor() Factor The two steps to creating a factor are: • Creating a vector • Converting the vector created into a factor using function factor() • implemented to represent categorical data • Stores data on multiple levels • the different values that the factor can take are called levels • can be stored as integers with a corresponding label to every unique integer

• In Rlanguage when we create a data frame, its column is categorical data and hence a factor is automatically created on it. We can create a data frame and check if its column is a factor.

Data Frames • usedto store the tabular data • Data Frames are data displayed in a format as a table. Data Frame is a set of equal length vectors. The vectors could be of different data types • Data Frames can have different types of data inside it. • While the first column can be character , the second and third can be numeric or logical . However, each column should have the same type of data..
