R language--a sword of data analysis

R language , I call it a sword of data analysis .

Why do you say that?

First let's look at what is data analysis? The so-called data analysis is a series of scientific processes driven by commercial purposes to obtain data, process data, analyze data, display data and compose reports. And the R language has the corresponding method to be able to process and complete the content which the data analysis involves.

Next, let's think about these questions.

What is the R language? Why use the R language? How to learn R language?

First question: You can refer to the R official website (http://www.r-project.org), R is a free, open source software environment and platform intended for statistical calculations and drawings. However, what the R language can do now is far beyond its original purpose, and can be applied in many fields, such as data mining, machine learning, social networking, bioinformatics, financial data analysis, etc.

The second question: whether to use this tool, first of all to see whether the tool can solve the problem, that is, for the data analysis of all aspects of the problem, the R language can be very good, second, consider the cost of the tool, R language is free open source, R language easy to learn, and has a lot of resources and active community Finally, thinking about the performance of the tool, R language continues to evolve, performance is further optimized and improved, and can be mixed with other programming languages.

The third question: My proposal is "more than three" spirit, a need to learn more, learning is endless. Learning R Books, learning R information, learning R source code, learning R case, and so on , the second to practice, the practice of knowledge. combined with their own industry background, for their own problem domain, actively try to use the R language to analyze and answer, through the continuous practice of understanding and application of R; three to share, I for everyone, everyone for me. It is also convenient for you to embrace a shared heart and give convenience to others.

Some of the R language learning materials, I give friends to do the following recommendations.

1 R official website

22 Book "R Language Combat" and "R Programming Art"
