These functions extend autoplot.sp() and autoplot.elev() and return not a single plot but a list of plots. They are particularly useful if you want to print a .pdf file with one plot per page. They automatically plot the variables sp and elev of a ForestGEO-like dataset of class 'sp' or 'sp_elev'.

  • Create a 'sp' object with:

    object <- sp(DATA-WITH-VARIABLE-sp)
  • Create a 'sp_elev' object with:

    object <- sp_elev(DATA-WITH-VARIABLE-sp, DATA-WITH-VARIABLE-elev)

See sections Usage and Examples.

# S3 method for sp_elev
autoplot_by_species(object, species = "all",
  fill = "black", shape = 21, point_size = 3, contour_size = 0.5,
  low = "blue", high = "red", hide_color_legend = FALSE,
  bins = NULL, add_elevation_labels = TRUE, label_size = 3,
  label_color = "grey", xyjust = 1, fontface = "italic",
  xlim = NULL, ylim = NULL, custom_theme = NULL, ...)

# S3 method for sp
autoplot_by_species(object, species = "all",
  fill = "black", shape = 21, point_size = 3,
  hide_color_legend = FALSE, xlim = NULL, ylim = NULL,
  custom_theme = NULL, ...)

Arguments

object

An object created with sp() or sp_elev().

species

A character vector giving values in the column sp. The output will be a list with as many plots as elements in this vector. The string "all" (default) plots all unique values of sp.

fill

Character; either a color or "sp", which maps each species to a different color.

shape

A number giving point shape (as in graphics::points()). Passed to ggplot2::geom_point().

point_size

A number giving point size. Passed to ggplot2::geom_point().

contour_size

A number giving the size of the contour of elevation lines. Passed to ggplot2::stat_contour() (see ggplot2::geom_contour()).

low, high

A string giving a color of the elevation lines representing low and high elevation.

hide_color_legend

Logical; TRUE hides the color legend.

bins

A number giving the number of elevation lines to plot.

add_elevation_labels

Logical; FALSE hides elevation labels.

label_size, label_color, fontface

A number (label_size) or character string (label_color and fontface) giving the size, colour and fontface of the text labels for the elevation lines.

xyjust

A number to adjust the position of the text labels of the elevation lines.

xlim, ylim

A vector of length 2, for example c(0, 500), giving the minimum and maximum limits of the vertical and horizontal coordinates.

custom_theme

A valid ggplot2::theme(). NULL uses the default theme theme_default().

...

Not used (included for compatibility across methods).

Value

A list of objects of class "ggplot".

Details

autoplot_by_species(sp_elev(DATA-WITH-VARIABLE-sp) (without elevation data) is equivalent to autoplot_by_species(sp(DATA-WITH-VARIABLE-sp)).

fgeo.plot wraps some functions from the ggplot2 package. For more control you can use ggplot2 directly.
