#Rename column r series#
This is part of our larger series about manipulating data in R.
#Rename column r code#
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 column r software#
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. Especially when adding new data frame columns and new column names, it is important to keep track of every single column value and character vector properly, or it will be impossible to keep all of the variable names straight in your string or matrix.Īgain, we need to stress the danger of using this approach if you expect to change your data frame design in the future. We can start by changing it to “days” if we were running a complicated experiment, additional description is good- that’s where using R to rename your columns comes in handy.
So, we are going to change that column name to make it more explicit. Then we would have a good start on a mess. Who knows, we might even merge it with other data frame that also has a Time column.
The “Time” column name is vague – there are multiple units of time. You can easily load the dataset into R by typing data(ChickWeight) into the R interpreter. 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.
