参数定义:
x | A numeric matrix of data, or an object that can be coerced to such a matrix (such as a numeric vector or a data frame with all numeric columns). |
centers | Either the number of clusters or a set of initial (distinct) cluster centres. If a number, a random set of (distinct) rows in x is chosen as the initial centres. |
iter.max | The maximum number of iterations allowed. |
nstart | If centers is a number, how many random sets should be chosen? |
algorithm | character: may be abbreviated. x为输入的数据集,centers为聚类的个数或者是初始的类中心,那么这个nstart又表示什么意思呢?不明白。 请达人再次赐教。 |
