Easily Visualize Data from 'ERDDAP' Servers via the 'rerddap' Package.

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, ...)
