autoplot.sp_elev {fgeo.plot}

Plot species distribution and/or topography.

Description

Plot the columns sp and/or elev of ForestGEO-like datasets of class 'sp' and/or 'sp_elev'.

• You can create a 'sp' object with:

    object <- sp(DATA-WITH-VARIABLE-sp)

• You can create an 'elev' object with:

    object <- elev(DATA-WITH-VARIABLE-elev)

• You can create a 'sp_elev' object with:

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

See Examples below.

Usage

## S3 method for class 'sp_elev'
autoplot(
  object,
  fill = "sp",
  hide_fill_legend = FALSE,
  shape = 21,
  point_size = 3,
  facet = TRUE,
  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,
  ...
)

Arguments

object

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

fill

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

hide_fill_legend

Logical; TRUE hides the fill legend.

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().

facet

Logical; TRUE wraps multiple panels within the area of a single graphic plot.

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).

Details

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

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

Value

A "ggplot".

# Species ---------------------------------------------------------------

# Small dataset with a few species for quick examples
census <- fgeo.x::tree5 %>%
  subset(sp %in% c("PREMON", "CASARB"))

autoplot(sp(census))

# Skip R CMD check for speed

# Customize
autoplot(sp(census), point_size = 1)

# Elevation -------------------------------------------------------------

elevation <- fgeo.x::elevation
autoplot(elev(elevation))

# Skip R CMD check for speed
# Same as `autoplot(elev(elevation))`
autoplot(elev(elevation$col))

# Customize
autoplot(elev(elevation), contour_size = 1)

# Species and elevation -------------------------------------------------
autoplot(sp_elev(census, elevation), facet = FALSE, point_size = 1)
