[英]How can I set different directory to the current directory in R?
I'm trying to open a file that does not exist in my current directory. 我正在尝试打开当前目录中不存在的文件。 This file is named
testFile.r
existing in the data
folder in my current directory. 该文件名为
testFile.r
存在于我当前目录的data
文件夹中。 I tried file.path("./data")
and then wanted to show the file with this command file.show("testFile.r")
but it gives this error: 我尝试了
file.path("./data")
,然后想要使用此命令file.show("testFile.r")
显示文件,但是它给出了此错误:
Error: File testFile.r does not exist.
错误:文件testFile.r不存在。
And the command getwd()
gives the previous current directory. 然后命令
getwd()
给出先前的当前目录。 So any thoughts on this? 那么对此有何想法?
You change your current directory using the command setwd(new_directory)
(replacing new_directory
with the path to the directory you want). 您可以使用命令
setwd(new_directory)
更改当前目录(将new_directory
替换为所需目录的路径)。
If you'd rather stay in your current directory, just do 如果您希望保留在当前目录中,只需执行
file.show("./data/testFile.r")
To keep track of multiple paths, you can save each as a variable and use the paste function to reference the file: 要跟踪多个路径,可以将每个路径另存为变量,然后使用粘贴功能来引用文件:
path1 <- "./data/"
path2 <- "./second_folder_name/"
file.show(paste0(path1, "testFile.R"))
file.show(paste0(path2, "testFile.R"))
