如何在R中写入距离函数？ [英] How do I write a distance function in R?
问题描述
距离
写一个函数find_distance（），它返回两个给定点之间的距离。你应该能够像这样调用函数：
＃point-1和point-2的坐标
p1< - c （0,0）
p2< - c（1,1）
find_distance（p1，p2）
中点
编写一个函数find_midpoint（），它返回两个给定点之间的中点。你应该能够像这样调用函数：
p1< - c（0,0）
p2< - c （1,1）
find_midpoint（p1，p2）
斜率
写一个函数find_slope（）返回连接线的斜率两个给定点。
您应该能够像这样调用函数：
p1< - c（0,0）
p2 < -c（1,1）
find_slope（p1，p2）
拦截
写一个返回截距的函数find_intercept（）连接两个
给定积分的线。此函数必须在内部使用find_slope（）
我尝试过：
我需要用于循环，这是在R.请帮忙！我是编程新手，我完全迷失了
Distance
Write a function find_distance() that returns the distance between two given points. You
should be able to call the function like this:
# coordinates for point-1 and point-2
p1 <- c(0, 0)
p2 <- c(1, 1)
find_distance(p1, p2)
Midpoint
Write a function find_midpoint() that returns the midpoint between two given points. You
should be able to call the function like this:
p1 <- c(0, 0)
p2 <- c(1, 1)
find_midpoint(p1, p2)
Slope
Write a function find_slope() that returns the slope of the line connecting two given points.
You should be able to call the function like this:
p1 <- c(0, 0)
p2 <- c(1, 1)
find_slope(p1, p2)
Intercept
Write a function find_intercept() that returns the intercept of the line connecting two
given points. This function must internally use find_slope()
What I have tried:
I need to use for loops, This is in R. Please help! I am new at programming , and I am completely lost

所以，你没有尝试自己解决问题，毫无疑问，你只是想让我们做你的HomeWork。 br />
家庭工作问题是你在现实生活中必须解决的问题的简化版本，他们的目的是学习和练习。
我们不做你的HomeWork。
HomeWork不会测试你乞求别人做你的工作的技巧，它是让您思考并帮助您的老师检查您对所学课程的理解以及您应用这些课程时遇到的问题。
你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。
你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。
所以，试一试，重读课程并开始工作。如果您遇到特定问题，请显示您的代码并解释这个问题，我们可能会提供帮助。
作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会如何。而且越快越好。
当你要求解决方案时，就像试图通过培训其他人来学习开车一样。
创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。
So, you show no attempt to solve the problem yourself, you have no question, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
