getAnywhere 该函数可以返回一些函数的R源代码,如: getAnywhere(kmeans) 该函数具体用法,请参看官方说明. Retrieve an R Object, Including from a Namespace Description These functions locate all objects with name matching their argument, whether visible on the search path, registered as
主要是运用递归的思想,函数主要两个参数,point是上一次取到的位置,picked主要记录在数组b中所取的元素的个数,函数的每一轮递归都会取一个数. package pack; import java.util.*; public class demo_1 { static int r,n; static int a[]=new int [100]; static int b[]=new int[100]; static void f(int point,int picked) { if(p
