从全局环境中选择数据框并将其导入到列表中

Question

I would like to select and import ca. 30 dataframes from my global environment into a list. All my dataframes end with ".AM", therefore should be very easy to import them but I am still quite new to R.

I tried:

mylist <- list(pattern = "*.AM")

but it doesn't work.

Answer 1

我们可以使用mget返回list的数据集。

mget(ls(pattern =  "*.AM"))

Answer 2

you are looking for

mylist <- ls(pattern = ".AM")

which returns mylist as a vector of the matching object names

Answer 3

try to set the working directory to wherever the files are saved

setwd("C:\\user\\files")

then create a list of the .AM dataframes

mylist = list.files(pattern="*.AM") 

I guess that should work?
