VisualizeSpatial: Visualize WRF Hydro domain spatial data.

In mccreigh/rwrfhydro: R tools for the WRF Hydro Model

Description

VisualizeSpatial creates basic plots of spatial data covering WRF-Hydro domain.

Usage

VisualizeSpatial(input, varName = "Variable", plot = TRUE,
  plotDf = NULL)

Arguments

input	A 2D array of data matching domain file.
varName	Character string specifying name of variable being plotted. Optional.
plot	Logical: plot or not?
plotDf	An optional data frame with the data from file already reprojected.

Details

Crude plots of the WRF Hydro spatial data. The routine accepts a grid of spatial data for either the geo (coarse resolution) or hydro (fine resolution) files. The return is a function (a closure which encapuslates the domain data) which creates a plot when called. The arguments to the function can be changed to tailor the plot (arguments are passed to ggmap and ggplot inside the function). This function (the closure) returns a ggplot object whose data can be accessed.

Value

A function which can be called to plot the data and allow adjustment of its arguments, the plotting parameters.
