The topics most related to this one relate to cleaning up a data frame: how to remove a column in R and remove rows in R. This is part of our larger series about manipulating data in R. flexibility your want when you write your project code and set data frame column names. Just to be sure to think about the balance of speed vs. And as we demonstrated, it isn’t hard to change column names in R. By changing your column names into easily remembered references, you simplify future updates to your projects. Changing column names in your data frame so they are easy to understand can significantly simplify your life.Īnd that concludes our summation of how to rename a column in R. As you move from doing solo projects and projects with highly structured releases to supporting a business team, being able to pass projects to another analyst and quickly resume work from months or years ago is a crucial skill. This is an especially important tip for folks transitioning from academia to industry. Rename (my_shiny_new_field = names(.)) Why This MattersĪ good tip from traditional software development is that you easily spend as much time reading your code as writing it, particularly when you are working as part of a larger team. We suggest turning the column names into a vector and using the index to select the right name from that vector to rename a column in r. with the more recent releases, you need to use a different approach to get the dplyr rename column by index function to work. You were previously able to directly use column index references in this package. They changed it a couple of releases ago the current syntax is # rename column in r dplyr If you’re working with the dplyr package to manipulate your data, there is a rename function. There’s almost always more than one way to get things done in R. Remapping fields based on name is a much safer way to proceed, of course, if you have time. That being said, this can be an excellent quick and dirty solution for throwaway data hygiene scripts if you’re in a hurry. There is a substantial burden from using a brittle system like column position. You can easily load the dataset into R by typing data(ChickWeight) into the R interpreter.Īgain, we need to stress the danger of using this approach if you expect to change your data frame design in the future. As you may remember, the ChickWeight data set includes four existing table columns: We want to make it easier to understand by changing column names in R, and getting rid of anu null value issue or missing values in a column header. For our first example of how to change column names in r, we’re going to use the the ChickWeight data frame and replace values within an existing dataframe column. Let’s take a look at how to change dataframe column names in R. The same goes for your data type: you will likely want to rename columns in your data frame to make it easier to understand and maintain each query and parameter over time, so that the field names in your dataframe can be understood and used in a regular expression, without confusion. How often have you had to dust off your work six months later? Explain your ideas to a new hire? Debug the system at 3AM? Clean crisp code is your friend in these moments. I came to R from the Python language, which makes readability a key priority for developers. You should consider clear and specific column names as part of your official project documentation. Learning how to change column name in R is an essential skill.
