Draw circle using reference points

Question

I have a dataset head that contains two variables x and y that represent points in the contourn of a circle. I try to draw the circle using this code

ggplot(head, aes(x=x, y=y))+geom_line()

However, the plot I get is this one

Could you help me to fix this? I really need to use those points. Thanks.

you want `geom_path`. probably a dup https://stackoverflow.com/questions/6862742/draw-a-circle-with-ggplot2 — , Jul 12 '19 at 06:54

try using geom_path. It connects observations in data order geom_line connect observations ordered by x value.

If your data is not ordered ok, you can order it by computing angle

head <- head %>% mutate(r = atan2(y, x)) %>% arrange(r)
