读取R中的多个csv文件 [英] reading multiple csv files in R

问题描述

我要读取R中的多个档案

档案位置（和名称）为：

 C：/Users/rohit.gupta/Desktop/Data For Rohit / PacketDetails / DUMP_DATA_PktLevel_1.csv
C：/Users/rohit.gupta/Desktop/Data For Rohit /PacketDetails/DUMP_DATA_PktLevel_2.csv
C：/Users/rohit.gupta/Desktop/Data For Rohit / PacketDetails / DUMP_DATA_PktLevel_3.csv
  

直到 DUMP_DATA_PktLevel_100.csv

如何做到这一点？ ？

解决方案

如果你的csv文件都是在你的目录中找到的.csv文件，你可以通过使用@Jilber来修改@ list.files（）函数：

  fileList< -  list.files（path =C：/Users/rohit.gupta/Desktop/Data For Rohit / PacketDetails，pattern =。csv）
 sapply（fileList，read.csv）
   
 
 
您也可以限制 list.files（）使用正则表达式，请参见？regex 。 
 
I want to read multiple files in R

the file location(and name) being:
"C:/Users/rohit.gupta/Desktop/Data For Rohit/PacketDetails/DUMP_DATA_PktLevel_1.csv"
"C:/Users/rohit.gupta/Desktop/Data For Rohit/PacketDetails/DUMP_DATA_PktLevel_2.csv"
"C:/Users/rohit.gupta/Desktop/Data For Rohit/PacketDetails/DUMP_DATA_PktLevel_3.csv"
till DUMP_DATA_PktLevel_100.csv

How can this be done??
解决方案
If your csv files are all the .csv files found in your directory you can modify the answer of @Jilber by using the list.files() function as such:
fileList <- list.files(path="C:/Users/rohit.gupta/Desktop/Data For Rohit/PacketDetails", pattern=".csv")
sapply(fileList, read.csv)
You can also limit the files selected by list.files() using regular expression, see ?regex.
