R数组操作 [英] R array manipulation

问题描述

在Python列表可切片这样的 X [4：0] 从第四去的最后一个元素

In python lists can be sliced like this x[4:-1] to get from the fourth to the last element.

在类似的能为向量与 X来完成ř东西[4：长度（X）] 并与一些多维数组像 X [ ,,,, 4：昏暗（X）[5] ,,,] 。这是数组从元素中间切片特定维度到最后一个元素更加优雅的语法？

In R something similar can be accomplished for vectors with x[4:length(x)] and for multidimensional arrays with something like x[,,,,4:dim(x)[5],,,]. Is this more elegant syntax for array slicing for a particular dimension from an element in the middle to the last element?

推荐答案

您可以使用下拉元素语法：

You could use the drop elements syntax:

> (1:10)[-(1:4)]
[1]  5  6  7  8  9 10
