compare_two_years: compare_two_years

In USGS-R/AWUDS: wateRuse data analysis functions

Description

Returns scatter plot for 2 years for data elements of interest. Option to narrow down data geographically

Usage

compare_two_years(w.use, data.elements, year.x.y, area.column,
  areas = NA, legend = FALSE, pctDiff = 0, valDiff = 0,
  log.oper = "and", c.palette = c("#999999", "#E69F00", "#56B4E9",
  "#009E73", "#F0E442", "#0072B2", "#D55E00", "#CC79A7"))

Arguments

w.use	dataframe, the water use data
data.elements	chr, vector of data elements to be plotted (1 plot per element)
year.x.y	int, 2-element vector specifying the two years to be plotted
area.column	character that defines which column to use to specify area
areas	chr, codes indicating HUCs, counties, states, aquifers, etc.
legend	is a logical function to include list of counties in a legend if manageable, default is FALSE
pctDiff	is the percent difference outlier criterion , default is zero
valDiff	is the value difference outlier criterion, default is zero
log.oper	indictaes the logical operator between the two outlier criteria, default is "and"
c.palette	color palette to use for points

Examples

w.use <- wUseSample
data.elements <- c("PS.TOPop", "PS.SWPop")
areas <- "10" # NA uses all areas
area.column <- "STATECODE"
year.x.y <- c(2005,2010)
compare_two_years(w.use, data.elements, year.x.y, area.column, areas)
compare_two_years(w.use, data.elements, year.x.y, area.column)
compare_two_years(w.use, "PS.TOPop", year.x.y, area.column)
pctDiff <- 10
valDiff <- 0
compare_two_years(w.use, "PS.SWPop", year.x.y, area.column, pctDiff, valDiff)
