基于R语言的统计数据柱形图的实现研究

摘要

In the era of big data, people not only need to extract useful data from big data, but also use the related software to analyze the data and make the data convenient for people to accept. At present, the visualization of statistics is paid more and more attention by the majority of applied researchers. In particular, statistics-based visualization of statistics has been studied by many statisticians, information scholars and computer scientists. Column diagram is the most common icon type, and it is suitable for many types of data. The information expressed by the stacked and grouped column diagrams in the column diagram is more intuitive and abundant. In the environment of R language, the program function language of the column diagram is given. Combined with the actual statistical data, a concrete case is given to realize the columnar diagram.%在大数据时代,人们不仅要从大数据中提取有用的数据,也要用相关软件来统计数据、分析数据,让这些数据方便使人接受.目前统计数据的可视化受到广大应用研究者的重视,特别是统计数据的基于统计图形的可视化得到了许多统计学者、信息学者、计算机学者的研究.柱形图是最常见的图标类型,柱形图适用于多种类型的数据,柱形图中的堆积柱形图和分组柱形图表达的信息更加直观丰富.在R语言的环境下,给出了柱形图的程序函数语言,并结合实际统计数据给出了实现柱形图的具体案例.
