如何使用R重命名文件? [英] How do I rename files using R?

问题描述

我在一个名为的文件夹中拥有700多个文件: 从1号到9号的文件在第一个月被命名:

I have over 700 files in one folder named as: files from number 1 to number9 are named for the first month:

water_200101_01.img  
water_200101_09.img  

从10号到30号的文件被命名为:

files from number 10 to number30 are named:

water_200101_10.img
water_200101_30.img

第二个月，依此类推: 从1到9的文件被命名为:

And so on for the second month: files from number 1 to number9 are named:

water_200102_01.img  
water_200102_09.img  

从10号到30号的文件被命名为:

files from number 10 to number30 are named:

water_200102_10.img
water_200102_30.img 

如何在不对文件进行任何更改的情况下重命名它们.只需更改名称，例如

How can I rename them without making any changes to the files. just change the nams, for example

water_1
water_2
...till...
water_700

推荐答案

file.rename将重命名文件，并且可以同时使用from和to名称的向量.

file.rename will rename files, and it can take a vector of both from and to names.

所以像这样:

file.rename(list.files(pattern="water_*.img"), paste0("water_", 1:700))

可能会工作.

如果要特别注意顺序，则可以对当前存在的文件列表进行排序，或者按照特定的模式进行排序，只需直接创建文件名向量即可(尽管我注意到700不是30的倍数)

If care about the order specifically, you could either sort the list of files that currently exist, or if they follow a particular pattern, just create the vector of filenames directly (although I note that 700 is not a multiple of 30).

我将搁置一个问题，你为什么要?"因为您似乎要丢弃文件名中的信息，但是大概该信息也包含在其他位置.

I will set aside the question, "why would you want to?" since you seem to be throwing away information in the filename, but presumably that information is contained elsewhere as well.
