Usually when I write my own code, I try to make my functions vectorized, so that you can call them with both a single element or with a vector. But in this case, I wasn’t allowed to modify the code to make the function vectorized. So how do we easily vectorizepatient_name()without...
R has several built in functions. But sometimes you need to create your own functions for a specific purpose. This lesson explains how to create...
I realize that this is a slightly more complicated application, but in reality, this is a very common way to use case_when in R. We commonly use case_when to create new variables in a dataframe, in conjunction with the mutate function. EXAMPLE 4: Create new variable by multiple conditions...

Yes,arrange()is often combined with functions likefilter(),mutate(), andselect()for comprehensive data manipulation: How do I sort rows in descending order? To sort rows in descending order, use thedesc()function withinarrange(). How does arrange() handle NA values?
