使用R重命名文件夹中的多个文件 [英] rename multiple files in a folder using R

问题描述

我有一个文件夹，其中包含几个文件，这些文件以测量数据的日期命名.例如:"07182014.csv"，"07192014.csv" ...

I have a folder which contains several files named by the date the data was measured. For example: "07182014.csv","07192014.csv"...

由于我有多个测量站，因此我想在每个文件名之前添加站号，以用于区分目的.例如，文件"07182014.csv"将变为"N1_07182014.csv".

Since I have multiple stations for the measurements, I would like to add the station number before each file name for distinguish purposes. For example, the file "07182014.csv" will become "N1_07182014.csv".

我是R的新手，在大多数情况下，我都是在网络上搜索我的数据分析问题的解决方案.

I'm new to R, and most of the time I search the web for solutions to my data analysis problem.

有人可以帮我修改下面的代码，以便我可以正确地重命名文件夹中的所有文件吗?或者，如果可以提供其他更好的解决方案，那将是有帮助的！

Can someone help me revise the code I'm having below so I can properly rename all files in the folder? Or if any other better solution can be provided, that will be helpful!

setwd("C:\\data")
files <- list.files() 
sapply(files,FUN=function(eachPath){ 
file.rename(from=eachPath,to=sub(pattern="[$.csv]", paste0("N0_"),eachPath)) 
}) 

非常感谢！

推荐答案

这是我的答案:

folder = "C:\\data"
files <- list.files(folder,pattern = "*.CSV",full.names = T) 
   sapply(files,FUN=function(eachPath){ 
   file.rename(from=eachPath,to= sub(pattern="\\/", paste0("\\/N0_"),eachPath))
 })
