vector元素的删除 remove的使用 unique的使用 在vector删除指定元素可用以下语句 : v.erase(remove(v.begin(), v.end(), element), installed.end()); 可将vector中所有值为element的元素删除。 以上转自:http://blog.csdn.net/ozwarld/article/details/7761519 以下转自:http://blog.csdn.net/zlhy_/articl...

modCount是Vector对象持有的一个int变量,它本身位于Vector的父类AbstractList中,此处增加1,表示Vector的元素状态发生改变,迭代器那里会使用fail-fast,防止多线程下即遍历又删除,也防止单线程下,一边遍历元素、一边删除元素 2、检查下标是否存在元素 检查传入的下标index是否存在元素,当index与elementCount相等或者大于element...
vec<-c(5, NA,3,9, NA,4, NA)vec# 5 NA 3 9 NA 4 NA As you can see based on the output of the RStudio console, our example vectors contains four numeric values and threeNAs. Let’s remove these NAs… Example 1: Create New Vector without NA Values ...
