Produces a plot based on Endler's (1990) segment analysis.

segplot(
  segdata,
  labels = TRUE,
  lab.cex = 0.9,
  out.lwd = 1,
  out.lty = 1,
  out.lcol = "black",
  tick.loc = c(-1, -0.5, 0.5, 1),
  square = TRUE,
  margins = NULL,
  ...
)

Arguments

segdata

(required) a data frame, possibly a result from the colspace() or segspace() function, containing values for 'LM' and 'MS' as columns (labeled as such).

labels

logical. Should the name of each cone be printed next to the corresponding vertex?

tick.loc

a numeric vector specifying the location of tick marks on x & y axes.

square

logical. Should the aspect ratio of the plot be held to 1:1? (defaults to TRUE).

margins

Deprecated. Please use the standard par() method for custom margins.

...

additional graphical options. See par().
