Welcome to the world of Statistical Programming. The general syntax is the name of the variable, followed by$, followed by the name assigned: name_of_the_list_variable$name_assigned_to_element. We represent another vector, first_quarter_names, with names of the first three months. The product of the dimensions should be equal to the number of elements in all the input vectors. The upper ceil of the value is taken, and therefore, each row should contain 6 elements. Introduction to R Programming Over the past few years, R has been steadily gaining popularity with business analysts, statisticians and data scientists as a tool of choice for conducting statistical analysis of data as well as supervised and unsupervised machine learning. He is passionate about building tech products that inspire and make space for human creativity to flourish. To get the first quarter of the matrix, we’ll use the following code: With the solid knowledge of vectors, matrices, and various data types, let’s shift gears and move towards factors and lists. R has a broad index of statistical and graphical techniques. It involves the algorithms from machine learning, linear regression, time series, etc. R provides highly extensible graphical methods.
