我们如何读取CSV文件并将数据输入到R中的write。xport（）函数？

这里主要与我读取的csv数据转换为输入write.xport（）功能相混淆。我刚开始学习R。

谢谢！

以下是使用Baltimore City Employee Salary数据读取CSV文件的示例。

#
# City of Baltimore 2016 employee salary data
#

theFile <- "https://data.baltimorecity.gov/api/views/65ac-s4v5/rows.csv?accessType=DOWNLOAD"

download.file(theFile,
              "./data/baltimoreEmployeeSalaries2016.csv",
              method="wininet", # for Windows, use "curl" for OS X / Linux
              mode="w")

salaries <- read.csv("./data/baltimoreEmployeeSalaries2016.csv",header=TRUE,stringsAsFactors=FALSE)
head(salaries)

...和输出。

> head(salaries)
                   Name                      JobTitle AgencyID                        Agency               HireDate

5    $64365.00 $74770.82
6    $40019.00 $16283.26

此时，您可以使用write.xport(salaries,...)生成SAS导出文件。
