[R] named character question

[arun]

HI,

One more method to extract the code:
add1<-"200 W Rosamond St, Houston, TX 77076, USA"
 sub(".*\\s.*\\s.*\\s.*\\s.*\\s.*\\s([[:digit:]]{5}).*","\\1",add1)
#[1] "77076"

#or,
 sub(".*\\s+([[:digit:]]{5}).*","\\1",ttt)
#[1] "77076"


A.K.

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
