add_tabledap(
  plot,
  table,
  var,
  color = c("#132B43", "#56B1F7"),
  size = 1.5,
  shape = 19,
  animate = FALSE,
  cumulative = FALSE,
  ...
)

Arguments

plot

a plotdap object.

table

a tabledap object.

var

a formula defining a variable, or function of variables to visualize.

color

either a character string of length 1 matching a name in cmocean or a vector of color codes. This defines the colorscale used to encode values of var.

size

the size of the symbol.

shape

the shape of the symbol. For valid options, see the 'pch' values section on points. plot(0:25, 0:25, pch = 0:25) also gives a quick visual of the majority of possibilities.

animate

whether to animate over the time variable (if it exists). Currently only implemented for method='ggplot2' and requires the gganimate package.

cumulative

- if animation should be cumulative -default FALSE

...

arguments passed along to geom_sf() (if method='ggplot2', otherwise ignored).

Value

A plotdap object
