About using GAM Models in R

Currently I'm replicating the exercise did by Wood (2006) about the relationship between air pollution and death rates in Chicago, using GAM models.

So, I followed the code he used in his book. The library is called "gamair" and the data frame is "chicago".

I put this (exactly like the book):


But I got an error:

Error in s(time, bs = "cr", k = 200) : 
  unused argument(s) (bs = "cr", k = 200)

Somebody could explain me this?

Thank you so much.
