monitor_map: Static map of monitoring stations

Description Usage Arguments Details Examples

View source: R/monitor_map.R

Description

Creates a map of monitoring stations in a given ws_monitor object. Individual monitor timeseries are reduced to a single value by applying the function passed in as slice to the entire timeseries of each monitor with na.rm=TRUE. These values are then plotted over a map of the United States. Any additional arguments specified in '...' are passed on to the points() function.

If slice is an integer, it will be used as an index to pull out a single timestep.

If slice is a function (not a function name) it will be used with argument na.rm=TRUE to collapse the time dimension. Thus, any user defined functions passed in as slice must accept na.rm as a parameter.

Arguments

ws_monitor

ws_monitor object

slice

either a time index or a function used to collapse the time axis

breaks

set of breaks used to assign colors

colors

set of colors must be one less than the number of breaks

pch

Plot symbols used to draw points on the map.

cex

the amount that the points will be magnified on the map

stateCol

color for state outlines on the map

stateLwd

width for state outlines

countyCol

color for county outline on the map

countyLwd

width for county outlines

add

logical specifying whether to add to the current plot

...

additional arguments passed to maps::map() such as 'projection' or 'parameters'

Details

Using a single number for the breaks argument will result in the use of quantiles to determine a set of breaks appropriate for the number of colors.
