plotdap

The plotdap package makes it easy to map data acquired via the rerddap functions tabledap() or griddap().

Installation

You can install the released version of plotdap from CRAN with:

install.packages("plotdap")

The development version is available from Github and can be installed with:

devtools::install_github('ropensci/plotdap')

Functions

plotdap has four main functions and can produce plots in both base graphics and ggplot2 graphics, though certain features ony work wih ggplot2:

  • plotdap() which sets up the base map:

    • plotdap(method = c("ggplot2", "base"), mapData = maps::map("world", plot = FALSE, fill = TRUE), crs = NULL, datum = sf::st_crs(4326), mapTitle = NULL, mapFill = "gray80", mapColor = "gray90", ...)
  • add_tabledap() which adds the results from a rerddap::tabledap() call:

    • add_tabledap(plot, table, var, color = c("#132B43", "#56B1F7"), size = 1.5, shape = 19, animate = FALSE, cumulative = FALSE, ...)
  • add_griddap() which adds the results from a rerddap::griddap() call:

    • add_griddap(plot, grid, var, fill = "viridis", maxpixels = 10000, time = mean, animate = FALSE, cumulative = FALSE, ...)
  • add_ggplot() allows customization of the plot when ggplot2 is used:

    • add_ggplot(plot, ...)

Examples

Extensive examples are gven in the vignette, which can also be viewed at:
