By MicroRbt Martinez PhD
R语言函数名：anyDuplicated()
R语言函数功能：确定重复元素
来自资源库：基础库（R语言自带）
anyDuplicated()函数所属R语言包：所在R包具体名称、包功能的中英文双语描述见正文后面'--所在R语言包信息--'部分。
描述-----Description-----
duplicated() determines which elements of a vector or data frame are duplicates of elements with smaller subscripts, and returns a logical vector indicating which elements (rows) are duplicates.
duplicated()cc确定矢量或数据帧中的哪些元素是下标较小的元素的重复，并返回一个逻辑矢量，指示哪些元素（行）是重复的。
anyDuplicated(.) is a generalized more efficient shortcut for any(duplicated(.)).
anyDuplicated(.)是any(duplicated(.))的generalized更有效的快捷方式。
使用方法-----Usage-----
duplicated(x, incomparables = FALSE, ...)
## Default S3 method efault S3 method:
默认的S3方法：
duplicated(x, incomparables = FALSE,
fromLast = FALSE, nmax = NA, ...)
## S3 method for class 'array' S3 method for class 'array'
duplicated(x, incomparables = FALSE, MARGIN = 1,
fromLast = FALSE, ...)
anyDuplicated(x, incomparables = FALSE, ...)
## Default S3 methodefault S3 method:
默认的S3方法：
anyDuplicated(x, incomparables = FALSE,

## S3 method for class 'array' S3 method for class 'array'
anyDuplicated(x, incomparables = FALSE,
MARGIN = 1, fromLast = FALSE, ...)
参数-----Arguments-----
参数x介绍: a vector or a data frame or an array or NULL.
向量或数据帧或数组或NULL。
参数incomparables介绍: a vector of values that cannot be compared. FALSE is a special value, meaning that all values can be compared, and may be the only value accepted for methods other than the default. It will be coerced internally to the same type as x.
不可比较的值的向量。 FALSE是一个特殊值，表示可以比较所有值，并且可能是默认值以外的方法唯一接受的值。它在内部将被强制为与x相同的类型。
参数fromLast介绍: logical indicating if duplication should be considered from the reverse side, i.e., the last (or rightmost) of identical elements would correspond to duplicated = FALSE.
