Is there a way to use find and replace for multiple lines at once in R or RStudio?

Is there a way to use find and replace for multiple lines at once in R or RStudio?

Here is the data I'm using for this example:


# example data

## starting data

### mtcars
head(mtcars)
str(mtcars)
colnames(mtcars)


## ending data

### AirPassengers   
head(AirPassengers)
length(AirPassengers)
is.na(AirPassengers)

I know I can just use the find and replace buttons to change mtcars to AirPassengers by doing so 1 line at a time or by highlighting/copying/pasting, but I want to know if it's possible to change multiple lines at once in R or RStudio.

Thanks ahead of time.
