Dear R People:

Here is a goofy question:

I want to extract the zip code from an address and here is my work so far:

add1

? ? ? ? ? ? ? ? ? results.formatted_address
"200 W Rosamond St, Houston, TX 77076, USA"

add1[1][32:36]

<NA> <NA> <NA> <NA> <NA>
? NA?  NA?  NA?  NA?  NA

str(add1)

Named chr "200 W Rosamond St, Houston, TX 77076, USA"
- attr(*, "names")= chr "results.formatted_address"

What am I not seeing, please?

Thanks,
Erin
