Examples

d <- data.frame(
  baseline = c("G0", "G0", "G1", "G1", "G2", "G0"),
  followup = c("G0", "G1", "G1", "G2", "G2", "G0")
)
ggnext(d, aes(baseline, followup)) + geom_shift()
#> <ggnext plot>
#>   data:  6 x 2
#>   aes:   x = baseline, y = followup
#>   layers: 1 
#>   coord: cartesian
#>   mode:  static
