读取文件名称中包含每日日期的文件 [英] Read file with daily date in the file name

问题描述

每天我都会收到一个包含每日日期的文件，例如:res_20161216.csv

Every day I receive a file with the daily date in it, for instance: res_20161216.csv

我不知道如何自动每天读取其中包含每日日期的文件.

I have no idea how to automatically read every day a file with the daily date in it.

任何帮助将不胜感激！

推荐答案

如果与要读取的文件位于同一工作目录中，则文件名如下.否则，您将需要使用getwd()

If you're in the same working directory as the files to be read, then the name of file is as follows. Else you will need to check what your working directory is using getwd()

nameOfFile <- paste0("res_", format(Sys.Date(), "%Y%m%d"),".csv")
data <- read.csv(nameOfFile)
