《数据科学与数据分析》实验课作业 Week 4&6_Exercise 2 请按照RMarkdown_Submission_Template.Rmd进行作答，并将作答结果的pdf文档，上传到“教学立方”当中。 下列问题，均基于nycflights13包中的数据集，请预先下载此包。 Data sets in package ‘nycflights13’: airlines Airline names. airports Airport metadata flights Flights data planes Plane metadata. weather Hourly weather data 问题一：flights数据集中有origin和dest这两个变量，分别表示航班的起飞地点和达到地点。 • 统计一下总共有多少个不同的往返地组合，并将这些往返地组合抽取出来，构造成一个名为Ori.Dest的新数据集。 • airports数据集当中包含每个机场的经纬度信息。请将flights数据集进行扩充，增加4列（Ori.Lat, Ori.Lon, Dest.Lat, Dest.Lon），这4列分别表示起飞地的经纬度和到达地的经纬度。使用merge函数，熟悉此函数的不同用途。 （经度：Longitude；纬度：Latitude） • 构造一个名为Calculate_Distance的函数，该函数可以传递4个参数（上题的4个参数），根据这4个参数，计算出起飞地点和到达地点之间的距离。 • 为flights增加一列，名为Cal.Distance，这一新变量是上题计算出的起飞地和到达地之间的距离。 问题二：planes数据中，有每架飞机的tailnum（机尾编号），可作为飞机唯一标识符，完成下列问题： • 创建一个名为flights.Planes.Info的新data.frame，其中记录不同飞机的飞行次数、平均飞行距离、平均延误时间，并按照平均延误时间从大到下排序。（使用dplyr包中的一系列函数） • planes数据集中有一个变量叫manufacturer，表示该架飞机的制造商。请根据flights中的飞行次数，挑选出飞行次数最多的5家飞机制造商。 • 在问题2的基础上，将flights数据集中这5家飞机制造商的相关飞行记录提取出来，构造一个名为flights.Top5的data.frame。
