R command file.path

Question

file.path('folder1','folder2')
#[1] "folder1/folder2"  

What did command above do within my working directory? The response: [1] "folder1/folder2" is unclear

Answer 1

It doesn't do anything with your working directory; it makes the path and then you have to assign it to working directory:

> file.path('C:','Users')  
[1] "C:/Users"  
> getwd()  
[1] "C:/Users/T/Documents"  
> setwd(file.path('C:','Users'))  
> getwd()  
[1] "C:/Users"
