In USGS-R/USGSHydroTools: Collection of functions for hydrological analysis

Summarize dataDF by group

Description

Mapping routine that displays spatial dataDF variability by color differences. over layers with political boundaries, hydrologic polygons, and hydrologic lines.

Usage

summarizedataDF(dataDF, colGroup, colValue, colDate)

Arguments

dataDF	dataframe with columns defined by colGroup (grouping column, such as site ID), colValue (value column), and optionally colDate (date columns)
colGroup	string defines grouping column in dataDF
colValue	string defines value column in dataDF
colDate	string defines date column in dataDF. If colDate = NA, the calculations for start and end date are ignored.

Value

dataframe with count, mean, median, min, max, start(date/time), end(date/time), and number of non-detects (nd) defined as number of NA's grouped by colGroup

Examples

df <- data.frame(site=c("1","x","2","1","x","2"),
                 conc=c(2,3,4,5,NA,7),
                 dates=as.Date(c("2011-01-01","2011-01-01",
                   "2011-01-01","2011-01-02","2011-01-02","2011-01-02")))
sumDF <- summarizedataDF(df, "site", "conc", "dates")
