[Solved] How to calculate the mean of a group in R [closed]

by


Here you go.

library(dplyr)

Mean_of_a_group <- dataset %>% group_by(age_group) %>% summarize(happy = mean(happy))

I suggest using ggplot2 to do what you want here.

ggplot(data = Mean_of_a_group, aes(age_group, happy))+ geom_point

Dummy example

library(ggplot2)

ggplot(aes(x = disp, y= mpg), data = mtcars)+

geom_smooth(aes(colour = "red"), data = mtcars, stat = "smooth", formula = y ~ x , se = FALSE)+

geom_smooth(aes(coluor = "blue"), data = mtcars, stat = "smooth", formula = y ~ poly(x,2), se = FALSE)+

geom_point()
