Giving different colors to the dots that are in different intervals on a scatter plot in R-CodePudding

I am a beginner in R and would like to give different colors to the dots in my scatter plot, between 0 -> 0.4, 0.4 ->0.8 and 0.8 -> 1 in my x-axis. i have googled a lot but was not able to find hints for the solution.

i am using this code for the plot :

ggplot(xlim=1, ylim=1,) geom_point(data=df,aes(x1,y1)) 
  geom_circle(aes(x0 = x0, y0 = y0 ,r = r,colour=cb), data = circ_kv)  
  coord_fixed(xlim=c(0,1),ylim=c(0,1))

all help or hints are very much appreciated!

this is the scatter plot i am working with

Something like this?

library(tidyverse)

set.seed(1337)

data <- tibble(
  x = runif(300),
  y = runif(300)
)
  
data %>%
  mutate(
    # distance to origin
    r = sqrt(x**2   y**2),
    r_group = case_when(
      r < 0.4 ~ "group 1",
      r < 0.8 ~ "group 2",
      r < 1.0 ~ "group 3"
    )
  ) %>%
  ggplot(aes(x,y, color = r_group))  
    geom_point()  
    coord_fixed()
