quick_plot_field: Plot a field from an eps model

In andrew-MET/mepsr: Utilities for MEPS data

Description

Uses the output of read_members to quickly plot a field with a coastline map

Usage

quick_plot_field(eps_field, member, legend = TRUE, hires_coast = FALSE,
  col = fields::tim.colors(), num_rows = NULL, diff = FALSE,
  land_colour = "transparent", ...)

Arguments

eps_field	Output of read_members.
member	Member to plot. Can be numeric or one of "mean", "sd", or "all".
legend	Whether to plot a legend - TRUE or FALSE. Defaults to TRUE.
hires_coast	Plot a high resolution coastline - TRUE or FALSE. Defaults to FALSE.
col	Colour palette, i.e. a vector of colours. If breaks are specified there must be fewer colours than breaks.
num_rows	Number of rows in a multi member plot.
diff	Whether to plot the difference between 2 members. TRUE or FALSE. Only works if exactly 2 members are specified in the member argument.
land_colour	Fill colour for land in the plot. Default is transparent.
...	Arguments for image.plot, e.g. for breaks and colour palette.

Value

A plot

Examples

my_file <- get_data_filename(20180101, 0)
t2m <- read_members(my_file, "T2m", lead_time = 0)
quick_plot_field(t2m, 0)

breaks <- c(-50, -40, - 30, seq(-20, 15, 5))
colour_palette <- c("blue", "skyblue", "lightgreen", "green", "yellow", "gold")
colours <- colorRampPalette(colour_palette)(length(breaks) - 1)
quick_plot_field(t2m, 0, col = colours, breaks = breaks, lab.breaks = breaks)

library(viridis)
quick_plot_field(t2m, 0, hires = TRUE, col = viridis(256))

quick_plot_field(t2m, "all", legend = FALSE, num_rows = 2, col = viridis(256))
