named character question
It's best if you make these things available to us using dput() in the future. You're probably looking for the substr() function. Since _strings_ (not characters) in R are "primitive" (Not in the primitive/internal sense: just in the primordial sense) you can't subset them with the brackets operators: what you're doing is something closer to x <- 1:5 x[30: 35] Cheers, Michael

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 -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at gmail.com
