[R] dataRetrieval query error

[Rich Shepard]

I'm learning the dataRetrieval package. Following the example in Section
1.1.2 of the vignette (whatNWISdata) I prepared this script:
------
library("dataRetrieval")

siteNumbers <- c("14207920","14208000","14208200","14208300","14208500","14208600","14208700","14208850","14209000","14209100","14209250","14209500","14209600","14209670","14209700","14209710","14209750","14209775","14209790","14209900","14210000","14210005","14210020","14210025","14210030","14210100","14210150","14210152","14210160","14210200","14210255","14210400","14210480","14210490","14210500","14210530","14210535","14210600","14210650","14210676","14210750","14210760","14210765","14210800","14210830","14210850","14210900","14211000","14211004","14211005","14211006","14211008","14211010","14211023","14211494")

dataAvailable <- whatNWISdata(siteNumbers, service="all", parameterCD="all", statCD="all")
-----

The vignette says that for service, parameterCD, and statCD the default is
"all", but the package wants that explicitly. So that's what I did. Yet, my
syntax is still off:

> source("R-scripts/get-site-data-list.R") 
Error: All components of query must be named

Please show me what I'm missing.
