How to I update SPSS column labels in R?

Question

In SPSS there appears to be the column name and then the column "label" which is like a description of the column. If I load an SPSS file into R via haven and a look at the file with the "View" function, I can see the column label written under the column name in that "View" window. So it's there somewhere, but if I look at the tables attributes, I can't find it. It's been kinda hard to search for answers because it seems like SPSS's equivalent of factors are also called labels so most topics are about that. Have has a bunch of label functions, but they're all about the factor labels and not the column name labels. I really just want to access the column labels in R and update them.
