How can others who run my R program read a file(eg: csv) used in my R code without having to change the working directory in setwd()?

  • Where does the data come from? If you want to find files relative to your R script, maybe look at the [here package](https://here.r-lib.org/). Or are you using RStudio? If so, consider using RStudio projects. Read more about [project oriented workflows](https://www.tidyverse.org/blog/2017/12/workflow-vs-script/) – MrFlick Aug 06 '21 at 18:39

I will suggest you use the here() function in the here package in your code like this:

library(here)
Data1 <- read_csv(here("test_data.csv"))

read.csv has a file argument and if I were to quote from the inbuilt R help about file:

If it does not contain an absolute path, the file name is relative to the current working directory, getwd().

So, providing the absolute path of the file inside the file argument solves this problem.

In Windows

Suppose your file name is test.csv and it's located in D:\files\test_folder (you can get the location of any file from its properties in Windows)

For reading this file you run:

df<-read.csv('D:\\files\\test_folder\\test.csv')

or

df<-read.csv('D:/files/test_folder/test.csv')

Haven't used R in Linux but maybe Getting a file path in Linux might help

Read from web

Just type in the web address of the dataset in the file attribute. Try:

df<-read.csv('https://raw.githubusercontent.com/AdiPersonalWorks/Random/master/student_scores%20-%20student_scores.csv')

Note: This link contains a list of 25 students with their study hours and marks. I myself used this dataset for one of my earlier tasks and its perfectly safe
