Here are the steps on how to write code and set your working directory in R Programming on Mac and Windows:
Mac
- Open RStudio.
- Click on the "File" menu and select "New File".
- Select "R Script" from the list of file types.
- Save the file in a location that you will remember.
- In the RStudio console, type the following code:
getwd()
This will print the current working directory to the console.
- To change the working directory, type the following code:
setwd("/path/to/new/working/directory")
Replace `/path/to/new/working/directory` with the path to the new working directory.
Windows
- Open RStudio.
- Click on the "File" menu and select "New File".
- Select "R Script" from the list of file types.
- Save the file in a location that you will remember.
- In the RStudio console, type the following code:
getwd()
This will print the current working directory to the console.
- To change the working directory, type the following code:
setwd("C:/path/to/new/working/directory")
Replace `C:/path/to/new/working/directory` with the path to the new working directory.
Once you have set your working directory, you can load data files and run R scripts from that directory.
Linux
- Open RStudio.
- Click on the "File" menu and select "New File".
- Select "R Script" from the list of file types.
- Save the file in a location of your choice.
- In the R console, type the following code:
getwd()
This will print the current working directory to the console.
- To set the working directory to the location where your R script file is saved, type the following code:
setwd("/path/to/your/R/script/file")
Once you have set your working directory, you can load your data files and start writing code.
Note
- You can also set your working directory by clicking on the "Session" menu and selecting "Set Working Directory".
- You can use the `getwd()` and `setwd()` functions to get and set the working directory from within R code.
- You can create a default working directory by going to the "Tools" menu and selecting "Global Options". In the "General" tab, you can enter a path to a directory that you want to use as the default working directory.
- You can use the cd() command to change your working directory from the command line.
- You can also set your working directory by clicking on the "File" menu and selecting "Change Dir".
