Hello, This is certainly Abhishek Kumar, and welcome on the tenth module on R programming fundamentals, which happens to be Checking out Information With R. Nicely, to date her explanation in this course, we have tricky radius aspects of code R programming. Then in the earlier module, we figured out to import facts from various resources. Now, In this particular module, we will utilize the educational of former modules to take a look at, and extract information from the supplied dataset. So, In this particular module, you might find out to answer concerns like, supplied a dataset, what can you see about that dataset inside a wide feeling. So we will explore numerous crucial statistical indicators, which might help you to definitely summarize a dataset. We may also go over the consumer base R capabilities, to complete these kinds of variety of study.
