Rename columns coming back from NWIS data retrievals. Daily and unit value columns have names derived from their data descriptor, parameter, and statistic codes. This function reads information from the header and the arguments in the call to to rename those columns.
Usage
renameNWISColumns(
rawData,
p00010 = "Wtemp",
p00045 = "Precip",
p00060 = "Flow",
p00065 = "GH",
p00095 = "SpecCond",
p00300 = "DO",
p00400 = "pH",
p62611 = "GWL",
p63680 = "Turb",
p72019 = "WLBLS",
...
)Arguments

- p00010
the base name for parameter code 00010.
- p00045
the base name for parameter code 00045.
- p00060
the base name for parameter code 00060.
- p00065
the base name for parameter code 00065.
