I've scoured through so many forums trying to remove a vector of values from another vector and setdiff does exactly what I needed, thank you so much!!really
至此,执行delete (pBaseA);会输出NewB::PerfectFunctionName并且崩溃的来龙去脉应该已经清楚了。但是那个push 1到底是什么呢? 奇怪的 push 1 为了弄清这个push 1的来历与作用,我把delete pBaseA改成了delete((BaseB*)pBaseA);,这样代码会按正常的逻辑执行。 也就是会执行到NewB::'vector deleting destructor'...

In 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 vector # [1] 1 5 -3 2 2 -5 7...
