Draw SSM profile points in circumplex space

Source: R/geom_ssm.R
geom_ssm_point.Rd

A ggplot2 layer that places a point for each profile at its amplitude and displacement on a circumplex canvas built with coord_circumplex() (for example the canvas from ggcircumplex()). The amplitude and displacement are supplied directly in SSM units (amplitude in the score metric, displacement in degrees); the coordinate system performs the polar transform.

Usage

geom_ssm_point(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  amax = NULL,
  na.rm = TRUE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping, data, stat, position, show.legend, inherit.aes, ...

Standard ggplot2 layer arguments. mapping must supply the amplitude and displacement aesthetics.

amax

(Deprecated) The amplitude represented by the outer ring is now owned by coord_circumplex(); a value supplied here is ignored with a one-time note.

na.rm

If FALSE, warn (with the dropped-row count) before removing profiles with a missing displacement or amplitude, since they have no location on the circle; if TRUE (the default) remove them silently.

Value

A ggplot2 layer.

Examples

data("jz2017")
res <- ssm_analyze(jz2017, scales = 2:9, measures = "NARPD")
ggcircumplex(octants(), amax = 0.5) +
  geom_ssm_point(
    data = res$results,
    mapping = ggplot2::aes(amplitude = a_est, displacement = d_est)
  )
