To see what files are in this directory, you can either use the dir() function to print the list of files to the console, or in RStudio you can view the files in the Files tab of the bottom right pane (where you find plots, help, package listings, etc).įor example, in my current Rproject, the working directory isĭir( "./data/") "Baltimore_City_Employee_Salaries_FY2015.csv" In RStudio, this path is also displayed at the top of the console. To see where your current working directory is in your R sessions, you can use the function getwd() which prints the directory in the console. Some typical directory structure syntax elements include

Mac/Linux - The default directory structure already uses forward slashes, so you shouldn’t need to alter copied paths from these operating systems.

Windows - The default directory structure involves a single backslash "\", but R interprets these as escape characters, so you must replace the backslashes with forward slashes "/" or two backslashes "\\".

When setting the working directory, there are some finicky syntax issues that can occur between Windows and Mac users. When you open this R project, R will default the working directory to the folder containing the Rproj file. Set up an R project in the folder that contains your dataset files and R scripts.Set the working directory manually using the function setwd("/path_to_folder/").Go to Session > Set Working Directory and choose the folder that contains your dataset.There are several way to have R set to the desired directory folder on your computer. R “look”s for files on your computer relative to the working directory. When reading files, you will need to specify the path to where this file is on your computer.

These will produce the R code needed to import your data, which you can then save to a script to use again if you need to re-import the dataset.īefore we look at importing a real dataset, let’s talk about working directories.
