The plotdap package makes it easy to map data acquired
via the rerddap functions tabledap() or
griddap().
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('rmendels/plotdap')plotdap has six 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, ...)bbox_set() which resets the bounding box as well as
prepare the object foe interactive plotting:
add_griddap_contours() which adds contours to a
add_griddap() object:
add_griddap_contours <- function(p, data, var, n_breaks = 10L, breaks = NULL, lon_col = "longitude", lat_col = "latitude", color = "black", linewidth = 0.3, alpha = 1, crs = 4326L)Extensive examples are gven in the vignette, which can also be viewed at:
