How to use setwd() In R Language

Q: How to use setwd() In R Language

To get the current working directory in which we are in, we can use the getwd() function in R:

Since the sample.csv file is located in C:\Users\harsh\Desktop\w3wiki directory, hence we need to move to this directory. In R, we can move from the current working directory to any other directory using the setwd() function:

R

# Mark the current directory
setwd('C:\\Users\\harsh\\Desktop\\w3wiki')
 
# Read the sample.
dataframe <- read.csv('sample.csv', header=TRUE, 
                      stringsAsFactors=FALSE)
 
# view data
dataframe

Output:

Hence, we are able to read the sample.csv file now.
