There are four basic data types in R. In this lecture, we look at 3 main data types in R.
A vector is a sequence of data elements of the same data type. Here we cover the creation of vectors of each data type in R.
A matrix is a collection of data elements of the same data type in a two-dimensional rectangular layout. Here we cover the matrix construction in R.
When a variable can take only a set of values, it is necessary in most circumstances to treat it as a categorical variable with different levels. In this lecture, we see how to create factors and look at summary and levels of a factor.
