为什么R中的矢量指数1开始，而不是0？ [英] Why do vector indices in R start with 1, instead of 0?

问题描述

是什么，而不是通常<$ C $的原因，在研究矢量指数与 1 开始， C> 0 ？

What is the reason that vector indices in R start with 1, instead of the usual 0?

例如：

> arr<-c(10,20)
> arr[0]
numeric(0)
> arr[1]
[1] 10
> arr[2]
[1] 20

难道只是他们想存储有关矢量额外的信息，不知道在哪里把它除了存储为载体的第一要素？

Is it just that they want to store extra information about the vector and didn't know where to store it except as the vector's first element?

推荐答案

FORTRAN是从1开始的数学家阵列处理的载体，它始终与组件1开始，经过N.直线代数约定开始行和列的一种语言编号为1，进入到第N个为好。

FORTRAN is one language that starts arrays at 1. Mathematicians deal with vectors that always start with component 1 and go through N. Linear algebra conventions start with row and column numbered 1 and go through N as well.

下开始以零，因为指针运算，这是隐含的下面。 Java中的JavaScript，C ++和C＃也跟着从C。

C started with zero because of the pointer arithmetic that was implicit underneath. Java, JavaScript, C++, and C# followed suit from C.
