R Documentation

USGS Drought Plot

Description

This function is hijacked from a blog post by Laura DeCicco at https://waterdata.usgs.gov/blog/moving-averages/. I changed it a little to include compatibility with batch_USGSdv and also the ability to change the rolling average, e.g. rolln. For more details visit the blog. Also, this function is expensive so it will take about 5 to 15 seconds to produce plot depending on period of record.

Usage

plot_USGSdrought(
  procDV,
  site = NULL,
  rolln = 30,
  startDate = "2010-01-01",
  endDate = "2015-01-01",
  smooth.span = NULL
)

Arguments

`procDV`	A previously created batch_USGSdv object.`optional`
`site`	A USGS NWIS site. `optional`
`rolln`	A `numeric` number of days in moving average
`startDate`	A `character` indicating the start date.
`endDate`	A `character` indicating the end date.
`smooth.span`	A `numeric` value indicating the smoothing parameter for the loess function. If NULL (default) no smoothing will happen.
