R and Python are both data analysis tools that need to be programmed. Advanced fields of data mining and analysis, such as machine learning and text mining.Construct data analysis algorithms based on the business scenarios and actual problems.By reading R’s help files and the information on the network, you can solve specific problems relatively quickly. With these bases, when you encounter actual problems, you can find the R package you need to use. 10 days of centralized learning is enough for mastering the basic use, basic data structure, data import and export, and simple data visualization. Data analysis report output (R markdown).įrom my point of view, getting started with R is very simple.Statistical modeling (linear regression, logistic regression, tree model, neural network, etc.).
As far as our general data analysis or academic data analysis work is concerned, the things that R can do mainly include the following aspects. The functions of R cover almost any area where data is needed. Unlike Python, R, and other open source software, there is a charge for the genuine Excel.The built-in statistical analysis is too simple and has little practical value.The Excel data file itself can hold only 1.08 million rows without the aid of other tools, and it’s not suitable for processing large-scale data sets.When the amount of data is large, there will be a situation of stuttering.To fully master Excel, you need to learn VBA, so the difficulty is still very high.It can help you understand the meaning of many operations before further learning other tools (such as Python and R).You can do a lot of things with Excel: modeling, visualization, reports, dynamic charts, etc.Production of charts for some business magazines and newspapers (data visualization).Combine Word and PowerPoint to create data analysis reports.Simple statistical analysis for students or teachers (such as analysis of variance, regression analysis, etc.).Data management and storage of small and medium-sized companies.Data processing work under general office requirements.
