I am trying to change the borders of marked ellipses created using ggforce::geom_mark_ellipse(). How can I remove the borders and just keep the filled ellipses? code for reproducibility is provided below.
library(palmerpenguins)
library(tidyverse)
library(ggplot2)
library(ggforce)
penguins <- penguins %>%
drop_na()
penguins %>% head() %>% print()
p <- penguins %>%
ggplot(aes(x = bill_length_mm,
y = flipper_length_mm))+
geom_mark_ellipse(aes(colour=species, fill = species),
expand = unit(0.5,"mm"),
show.legend = F)+
geom_point(aes(color = species))
print(p)
>Solution :
You could remove the outline or set the thickness via size, i.e. size=0 or size=NA will work to remove the outline. Another option would be to set the linetype to blank, i.e. lty = "blank".

penguins <- penguins %>%

p <- penguins %>%
ggplot(aes(x = bill_length_mm,

geom_mark_ellipse(aes(colour=species, fill = species),
expand = unit(0.5,"mm"), size = 0,
show.legend = F)+
geom_point(aes(color = species))
print(p)
