whatData: Look for missing data for a set of samples

In USGS-R/WQ-Review: Discrete water-quality data review and exploration toolbox

Description

Searches for missing data and returns a dataframe of missing data by record number.

Usage

whatData(qw.data, searchParms, begin.date = NULL, end.date = NULL,
  groups = FALSE)

Arguments

qw.data	A qw.data object generater by readNWISodbc
searchParms	A character vector of parameter codes to search for if groups = FALSE, otherwise a dataframe of parameter codes in character format to search for grouped by named columns if groups= TRUE. Maximum number of columns(groups) is 10
begin.date	Subset data to begin date
end.date	Subset data to end date.
groups	Logical. Search for searchParms by groups instead of one long vector.

Examples

data("exampleData",package="WQReview")
searchParms <- data.frame(cations = c("00915","00930","00925","00935","01123"),
                          anions = c("00945","00940","99220",NA,NA),
                          nutrients = c("00608","00631",NA,NA,NA),
                          stringsAsFactors = FALSE)
whatDataOut <- whatData(qw.data = qw.data,
        searchParms = searchParms,
        begin.date = NULL,
        end.date = NULL,
        groups=TRUE)
