Remove shapes for the reference-sample points in iNEXT

[Ngoc Loi Nguyen]

Hi

I have tried to make rarefaction curves using iNEXT.

ggiNEXT(out, type=1, facet.var="order") +

  facet_wrap(~order, scales="free") +

  theme_bw(base_size = 18) +

  theme(legend.position="right") +

  theme_minimal() +

  scale_y_continuous(name="ASVs") +

  scale_x_continuous(name="Number of Reads")

  

How to remove 6 shapes for the reference-sample points with ggplot2?

Any idea about that?

Regards,

Loi.
