Applied Data Science with R in collaboration with IBM

R is actually an effective language for data analysis, data visualization, machine learning, stats. Initially created for statistical programming, it's currently one of the most favored languages in data science.

With this program, you will be to learn about the fundamentals of R, and you will end with the confidence to begin writing your very own R scripts. But this is not your normal textbook launch to R. You are not only understanding about R fundamentals, but you will also be using R to resolve problems related to films data. A concrete case can make learning painless. You are going to learn about the basic principles of R syntax, which includes assigning variables and doing small activities with R's most crucial details structures -- vectors! From vectors, you will then learn about data frames, arrays, matrix, and lists. After that, you will leap into conditional statements, functions, debugging and classes. As soon as you have covered the fundamentals - you will find out about reading and writing data in R, whether it is a table format(CSV, Excel) or maybe a text file (.txt). Lastly, you will end with a few crucial functions for character strings as well as dates in R.
