map_sites: map_sites

In USGS-R/wateRuse_swuds: Site-Specific Water-Use Data System

Description

Returns map of data element mapped by sites that have lat-lons Only works with one data element as currently written Assumes the s_wuds dataframe being used as input has already been subsetted using filter functions (by site type, state, or county, years, etc.) that is, no subsetting is done inside this function Dataframe must not have more than one row per site ID Point sizes are scaled to value

Usage

map_sites(s_wuds, data_element, year, state, norm_element = NA,
  unit_type = "county", site_from_to = "from")

Arguments

s_wuds	dataframe, the swuds water use data
data_element	chr, data element to be plotted
year	int, the year of interest to be mapped (defines historical basis for counties)
state	character name of state
norm_element	chr, element used to normalize data_element
unit_type	chr, type of unit to be mapped; acceptable options are "county", "huc", or "aquifer"
site_from_to	chr, either 'from' or 'to' to designate the site lats-lons to use; the 'from' site or the 'to' site

Examples

s_wuds <- swuds_sample #example data from OHIO
# subset for this example
s_wuds <- s_wuds[which(s_wuds$FROM_SITE_TP_CD == "AS" &
                       s_wuds$YEAR == 2010 &s_wuds$Month_num == 8),]
data_element <- "Volume_mgd"
state <- "Ohio"
year <- 2010
unit_type <- "county"
norm_element <- NA
sites.map <- map_sites(s_wuds, data_element, year, state)
sites.map
