Example 1: Delete Negative Elements from VectorIn Example 1, I’ll explain how to remove negative values from a vector object in R.For this example, we first have to create an example vector:vec <- c(1, 5, - 3, 2, 2, - 5, 7) # Create example vector vec # Print example ...
Remove Duplicates From a Vector in C++ Using std::sort and std::uniqueRemoval of duplicate elements from a vector in C++ can be efficiently achieved using the combination of std::sort and std::unique, two powerful functions provided by the C++ Standard Template Library (STL)....

vector之reserve和resize ,ersae和remove 1. vector 的reserve增加了vector的capacity,但是它的size没有改变!而resize改变了vector的capacity同时也增加了它的size。 reserve是容器预留空间,但在空间内不真正创建元素对象,所以在没有添加新的对象之前,不能引用容器内的元素。加入新的元素时,要调用push_back()/insert(...
Summary: You learned in this article how todelete vector elements that are NAin R. In case you have any further comments and/or questions, let me know in the comments. I’m Joachim Schork. On this website, I provide statistics tutorials as well as code in Python and R programming....
3. Usingstd::vector::resize Thestd::vector::resizefunction resizes the vector to contain the supplied number of elements. If the size is less than the vector’s size, all elements beyond the specified size are removed and destroyed. This can be used to remove elements from the end of a...
