将所有数据框保存在列表中以单独的.csv文件 [英] Save all data frames in list to separate .csv files

问题描述

我有一个要保存到独立的.csv文件的数据帧列表.

I have a list of data frames that I want to save to independent .csv files.

当前，我为每个数据帧添加了一行:

Currently I have a new line for each data frame:

write.csv(lst$df1, "C:/Users/.../df1")
write.csv(lst$df2, "C:/Users/.../df2")
ad nauseam

显然，这不是理想的选择:更改名称意味着要仔细检查每种情况并进行更新.我考虑过使用

Obviously this isn't ideal: a change in the names would mean going through every case and updating it. I considered using something like

lapply(lst, f(x) write.csv(x, "C:/Users/.../x") 

，但是那显然是行不通的.如何将列表中的每个数据框另存为单独的.csv文件?

but that clearly won't work. How do I save each data frame in the list as a separate .csv file?

推荐答案

您可以执行以下操作:

N <- names(lst)
for (i in seq_along(N)) write.csv(lst[[i]], file=paste0("C:/Users/.../"), N[i], ".csv")

在Heroka的简短评论之后:

Following the comment of Heroka a shorter version:

for (df in names(lst)) write.csv(lst[[df]], file=paste0("C:/Users/.../"), df, ".csv")

或

lapply(names(lst), function(df) write.csv(lst[[df]], file=paste0("C:/Users/.../"), df, ".csv") )
