named character question
Hi Erin, The first element of the character vector is a string. You cannot extract specifically characters from a string; try something like ?nchar or perhaps better use regular expressions to extract things between commas after two characters (or whatever logical rule accurately gets the zip code). Cheers, Josh

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
