Vector names()
Let's return to the example about January and February's returns. As a refresher, in January you earned a 5% return, and in February, an extra 2% return. Being the savvy data scientist you are, you realize that you can put these returns into a vector! That would look something like this:
ret <- c(5, 2)
This is great! Now all of the returns are in one place. However, you could go one step further by adding names to each return in your vector. You do this using names()
. Check this out:
names(ret) <- c("Jan", "Feb")
Printing ret
now returns:
Jan Feb
5 2
Pretty cool, right?
