(R) Kernal density curve /geom_density()/geom_line(stat="density") > ggplot(data=trees,aes(x=Volume))+geom_density() > ggplot(data=trees,aes(x=Volume))+geom_density() > ggplot(data=trees,aes(x=Volume))+geom_line(stat="density") As you can see below, setting geom_density(adjust=1) means nothing. There is no difference between ggplot(data=trees,aes(x=Volume))+geom_desity() and ggplot(data=trees,aes(x=Volume))+geom_density(adjust=1) because basic set for adjust in.. 2020. 9. 3.
