summary: how to read a row (not column) from a file into a vector (not a data frame)?


I'm using

$ lsb_release -ds
Linux Mint Debian Edition
$ uname -rv
3.0.0-1-amd64 #1 SMP Sun Jul 24 02:24:44 UTC 2011
$ R --version
R version 2.14.1 (2011-12-22)

I'm new to R (having previously used it only for graphics), but have worked in many other languages. I've got a CSV file from which I'd like to read the values from a single *row* into a vector. E.g., for a file such that

$ head -n 2 ~/data/foo.csv | tail -n 1

I'd like to be able to populate a vector 'v' s.t. v[1]=5718, ... v[43]=0

I can't seem to do that with, e.g., read.csv(...) or scan(...), both of which seem column-oriented. What am I missing?
