如何在R中定义变量的批次

我有很多文件可以在R中作为变量读取。当然，我们可以逐个读取它们，例如：

average<-read.csv("average.csv")
variance<-read.csv("variance.csv")
kurt<-read.csv("kurt.csv")
...

---

average最惯用的方法是使用与列表一起工作

file_names <- c("average.csv","variance.csv","kurt.csv")

# you can get nice names by using tools::file_path_sans_ext
library(tools)
names(file_names) <- file_path_sans_ext(file_names)

dataList <- lapply(file_names, read.csv)


# if you really wanted to copy these to the global environment as objects

list2env(dataList, env = globalenv())

文件名太棒了！你的建议真的很有帮助，非常感谢！
file_names <- c("average.csv","variance.csv","kurt.csv")

# you can get nice names by using tools::file_path_sans_ext
library(tools)
names(file_names) <- file_path_sans_ext(file_names)

dataList <- lapply(file_names, read.csv)


# if you really wanted to copy these to the global environment as objects

list2env(dataList, env = globalenv())
