In adamdsmith/pdsi: Retrieve, plot, and map Palmer Drought Severity Index data

Description

For description of PDSI index and drought/wetness levels, see the README at https://www1.ncdc.noaa.gov/pub/data/cirs/climdiv/drought-readme.txt

Usage

pdsi_plot(lat = NULL, lon = NULL, address = NULL, nyrs = 10,
  fill = c("RdBu", "BrBG", "PuOr"), halo = TRUE)

Arguments

lat	numeric scalar of position latitude (decimal degrees; WGS84)
lon	numeric scalar of position longitude (decimal degrees; WGS84)
address	character scalar of a street address or place name (e.g. "Mattamuskeet NWR" or "135 Phoenix Rd, Athens, GA"); overrides lat and lon if specified. See example
nyrs	numeric (default = 10); how many years before present would you like the initial graph to display?
fill	one of NULL, "RdBu" (default), "BrBG", or "PuOr". Color scheme to use to indicate the different drought/wet bands behind the PDSI time series. NULL suppresses the background fill.
halo	logical (default TRUE); display thin white border around PDSI time series line to aid viewing in more several categories

Examples

## Not run: 
pdsi_plot(34, -83)
