Thanks for the reply. In this instance, what's the syntax for map? I'm
trying in REPL and getting a wrong number of arguments (1) passed to
core$map.

I'm used to using the Python csv package and how that returns lines
from a csv. I could not get clojure-csv to split up the line the way I
wanted, and also thought about how to clojure.string/split the line.
Right now at the repl, I cannot figure out the syntax just to use map

Many thanks. I didn't recognize the % symbol is used similarly to the
way it's used in printf and constructing SQL query string.

Some resources, in case they help:
1. http://clojuredocs.org/ has documentation for core and contrib, and often
has examples
http://clojuredocs.org/2. http://clojure.org has a lot of reading material
about the language, including a nice cheat sheet (
http://clojure.org/cheatsheet)
3.
Also, you don't want to simply split the CSV into lines by looking for
newlines. CSVs can contain newlines quoted in fields, so you need to
actually parse the CSV with quoting to figure out the line breaks for
the file format and ignore the line breaks in the fields.

Thanks for your answer, David:
Eventually, I came back from reading a .csv file using a generic
method to closure-csv, and got help wrapping my mind around the data I
was getting back from closure-csv/parse and how to pull that apart to
get what I wanted.
I was also stuck on the notion of having
BTW I changed (:require [clojure.contrib.string :as str]) to (:require
[clojure.string :as str]) and the problem persists.
