- `std::vector`在一定程度上可以通过`at()`函数进行安全的边界检查访问。如果使用`at()`函数访问超出范围的索引，会抛出`std::out_of_range`异常，帮助程序员更容易地发现错误。- 例如：#include <iostream> #include <vector> int main() { std::vector<int> myVector = {1, 2, 3};try { std::c...

对于那些有一点编程经验的人来说,vector,matrix,array,list,data.frame就相当于编程语言中的容器,因为只是将R看做数据处理工具所以它们的底层是靠什么实现的,内存怎么处理的具体也不要深究。 R语言很奇怪的是它是面向对象的语言,所以经常会调用系统的方法,而且更奇怪的是总是调用“谓语”的方法,用起来像是写句子一...
