Let’s use the read.csv() function from the read.table package to load in a data set from the UCI Machine Learning Repository : An R tutorial on how to retrieve vector members with the square bracket operator. Discuss also the situations of negative and out-of-range indexes. When you use the read.csv command R uses a specific kind of variable called a “data frame.” All of the data are stored within the data frame as separate columns. If you are not sure what kind of variable you have then you can use the attributes command. This will list all of the things that R uses to describe the variable: 回答一位网友的问题： 1.原始数据为物种频数或频率，不能做取log值处理 2.指示值方法是寻找给定分组的标志物，故需要指定分组，文中的随机分组只是演示指示值方法的R用法 3.不需要每个每个分组数目一致，func参数设置是否要考虑每个分组数目不一样的影响，默认为IndVal.g，若不想考虑这个影响 R is an elegant and comprehensive statistical and graphical programming language.

If the association index used in multipatt is func = "IndVal" or func = "IndVal.g", one can also inspect the indicator value components when displaying the results. Indeed, the indicator value index is the product of two components, called ‘A’ and ‘B’ [Dufr^ene and Legendre, 1997][De C aceres and Legendre, 2009].
