Given our sample vector, apply the rank function: rank(x) [1] 4 1 3 2 The three functions have the same fundamental R syntax. The result of each function, however, is distinct. Sorting definition () The sort function in R returns data in ascending or descending order. As seen above,...

函数RData()实现从文件IN.dat中读取20行数据存放到字符串数组str中(每行字符串长度均小于80)。请编写函数stringSort(),其功能是:以行为单位对字符串按给定的条件进行排序,排序后的结果仍按行重新存入字符串数组str中。最后调用函数WData(),把结果str输出到OUT.dat文件中。 条件:从字符串中间一分为二,左边部分...
