\usage{
retrieveNWISqwData(siteNumber, pCodes, startDate, endDate, expanded = FALSE,
  interactive = TRUE)
}
\arguments{
\item{siteNumber}{string or vector of of USGS site numbers.  This is usually an 8 digit number}

\item{pCodes}{string or vector of USGS parameter code.  This is usually an 5 digit number.}

\item{startDate}{string starting date for data retrieval in the form YYYY-MM-DD.}

\item{endDate}{string ending date for data retrieval in the form YYYY-MM-DD.}

\item{expanded}{logical defaults to FALSE. If TRUE, retrieves additional information. Expanded data includes
remark_cd (remark code), result_va (result value), val_qual_tx (result value qualifier code), meth_cd (method code),
dqi_cd (data-quality indicator code), rpt_lev_va (reporting level), and rpt_lev_cd (reporting level type).}

\item{interactive}{logical Option for interactive mode.  If true, there is user interaction for error handling and data checks.}

\value{
data dataframe with agency, site, dateTime, value, and code columns
