Plot invasion graph using grammar of graphics
Usage
ggIG(
tbl,
node_size = 12,
node_stroke = 0.75,
node_color = c("grey", "black"),
node_fill = c(` TRUE` = "#FFFFFF", `invadable -i TRUE` = "#DDAA33", `saturated -i TRUE`
= "#2B5596", ` FALSE` = "#EEEEEE", `invadable -i FALSE` = "#FFD180",
`saturated -i FALSE` = "#809CDC"),
edge_color = c(multiple = "grey70", single = "grey40", `leaving -i` = "#DDAA33"),
edge_width = c(single = 0.5, multiple = 0.15),
text_color = "black"
)Arguments
- tbl
list containing an invasion graph and associated metadata
- node_size
numeric, size of the graph nodes/vertices
- node_stroke
numeric, size of the graph nodes/vertices outline
- node_color
colors of the graph nodes/vertices outline
- node_fill
colors of the the graph nodes/vertices fill
- edge_color
colors of the graph edge
- edge_width
numeric vector of line widths to use for multiple and single invasions
- text_color
color of the text labeling each node; may use named R colors or hex code
Examples
if (FALSE) { # \dontrun{
n <- 6 # set number of species
A <- -diag(n) - 1.5 * matrix(runif(n^2), n, n)
r <- matrix(1, n, 1)
sch <- inv_scheme(A, r)
gra <- inv_graph(IS = sch)
tidy_gra <- tidy_inv_graph(gra)
ggIG(tidy_gra)
} # }
