What is Current Working Directory in R?
You can see your current working directory by coding getwd (get working directory) function. getwd() function has no arguments. Therefore, just type it in R console. It returns an absolute filepath representing the current working directory of the R process.
getwd() ##  "C:/Users/DataScience/Desktop"

How to Change Working Directory in R
You can change your working directory with setwd (set working directory) function. The setwd() function includes an argument, a filepath of the desired working directory. Thus, I write the filepath of my working directory in setwd() function with double-quote to set my curent working directory to DataScience file in D drive.
Then, you can call your functions from your working directory. Before you call your functions, you can list the files in your working directory.
list.files() ##  "gplot"
Also, you can write your output/graphics to this directory. For example, I call gplot function from the working directory.
You can see the objects available in R console. For this purpose, just type ls() function in your R console.
ls() ##  "gplot"
Sometimes, you can not change working directory in R. The most probable reason of this is misspelling path of the file you want to work in. Also, you need to write the filepath in double-quote. Otherwise, you can not change working directory.
How to Clear Working Directory in R
After you set working directory, you may want to clear your working directory in R. For this purpose, we can use unlink() function.
unlink("D:/DataScience", recursive = TRUE)
