geom_sigmark_waves(tbl_sig, x = "wave_pos", y = "result_pos",
  group = NULL, direction = "Direction", labels = c("Increase",
  "Decrease"), colour = "level", fill = "level", icon = "full triangle",
  size = 5)

Arguments

tbl_sig

A df object created from tbl_sig functions.

x

A quoted character string of the variable from the 'tbl_sig' df charted on the x-axis. Typically this is "wave_pos".

y

A quoted character string of the variable from the 'tbl_sig' df charted on the y-axis. Typically this is "result_pos".

group

An optional quoted character string of the variable from the 'tbl_sig' df that is grouped. If needed, it likely needs to be "group".

direction

A quoted character string of the variable from the 'tbl_sig' df indicating whether the change from one wave to the next is up or down. Typically this is "direction".

labels

A quoted character string vector indicating how the sig. test markers should be labeled in the legend. By default, the labels are "Increase" and "Decrease".

colour

A quoted character string of the variable from the 'tbl_sig' df that applies the subgroup colours. Typically this is "level".

fill

A quoted character string of the variable from the 'tbl_sig' df that applies the subgroup colours. Typically this is "level".

icon

A quoted character string indicating the type of icon to display to denote statistical significance. Default is "full triangle".

size

A numeric value indicating the size of the icon. Default is set to 5.

Details

This is essentially a wrapper for geom_point

Note

The icon argument accepts one of the following strings:
