plot_field: Plot a single field in matrix form

In JGCRI/fieldgenr: Generate Temperature Fields with Spatial and Temporal Correlation

Description

Transform the field into a data frame using fld2df and plot using the ggplot2 package.

Usage

plot_field(
  fld,
  griddata,
  nb = 6,
  minval = -3.5,
  maxval = 3.5,
  legendstr = "Temperature (K)",
  palettestr = "RdYlBu",
  palettedir = -1
)

Arguments

fld	Vector of ngrid=nlat*nlon values: a single time slice of the field.
griddata	The griddata structure returned from read.temperatures.
nb	Number of breaks in the color scale. If nb < 2, use a smooth gradient.
minval	Lower limit of the color scale. The default value was chosen to work well for fields of residuals from the mean temperature response.
maxval	Upper limit of the color scale. The default value was chosen to work well for fields of residuals from the mean temperature response.
legendstr	String to use for the title of the graph legend
palettestr	String with the name of the ggplot2 color palette to use. Defaults to 'RdYlBu'. Options are Diverging: 'BrBG', 'PiYG', 'PRGn', 'PuOr', 'RdBu', 'RdGy', 'RdYlBu', 'RdYlGn', 'Spectral'; Qualitative: 'Accent', 'Dark2', 'Paired', 'Pastel1', 'Pastel2', 'Set1', 'Set2', 'Set3'; Sequential: 'Blues', 'BuGn', 'BuPu', 'GnBu', 'Greens', 'Greys', 'Oranges', 'OrRd', 'PuBu', 'PuBuGn', 'PuRd', 'Purples', 'RdPu', 'Reds', 'YlGn', 'YlGnBu', 'YlOrBr', 'YlOrRd'.
palettedir	Numerical value, only accepts 1 or -1, determining the order of the color palette used. Defaults to -1.
