    Description

    With its popularity as a statistical programming language rapidly increasing with each passing day, R is becoming the preferred tool of choice for data analysts and data scientists who want to make sense of large amounts of data as quickly as possible. R has a rich set of libraries that can be used for basic as well as advanced data analysis and machine learning tasks.
    So, if you're looking to understand how the R programming environment and packages can be used to for data analysis and machine learning, then you should surely go for this Learning Path.



    Packt’s Video Learning Path is a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.




    This Learning Path starts by organizing the data and then predicting it. You will work through various examples wherein you will explore RStudio and libraries, how to apply linear regression, how to score test sets, and plotting test results on a Cartesian plane. You will also see how to use logistic regression to predict for a classification problem on automobile data. Further, you will learn different ways to use R to generate professional analysis reports. Moving ahead, you will learn various important analysis and machine learning tasks that you can try out with associated and readily available data with the help of examples. Finally, you will learn advanced data analysis concepts such as cluster analysis, time-series analysis, PCA (Principal Component Analysis), sentiment analysis, and spatial data analysis.




    By the end of this Learning Path, you will have a solid understanding of how to efficiently perform data analysis and machine learning tasks using R.
