[英]Problem adding a trendline to a graph in R ggplot2
I tried to use geom_smooth(method = "lm")
and it doesn't work...我尝试使用
geom_smooth(method = "lm")
但它不起作用......
percentage.no.work <- cleanData %>% group_by(AREA) %>%
summarise(percentage = mean(ESTIMATED.CITY.UNEMPLOYMENT))
ggplot() +
geom_point(data=percentage.no.work, aes(x=AREA, y=percentage), alpha=0.6, color="purple", size=2) +
geom_smooth(method = "lm") +
theme_minimal() + ggtitle("Percentage Estimated City Unemployment") +
ylab("Percentage")
You need to provide the aesthetics for the geom_smooth
as well.您还需要为
geom_smooth
提供美感。 Either by including it in the ggplot()
or in the geom_smooth()
:通过将其包含在
ggplot()
或geom_smooth()
中:
ggplot() +
geom_point(data=percentage.no.work, aes(x=AREA, y=percentage), alpha=0.6, color="purple", size=2) +
geom_smooth(aes(x=AREA, y=percentage), method = "lm") +
theme_minimal() + ggtitle("Percentage Estimated City Unemployment") +
ylab("Percentage")
You can avoid repeating section of the code putting it in the ggplot()
您可以避免将代码的重复部分放入
ggplot()
ggplot(data=percentage.no.work, aes(x=AREA, y=percentage)) +
geom_point(alpha=0.6, color="purple", size=2) +
geom_smooth(method = "lm") +
theme_minimal() + ggtitle("Percentage Estimated City Unemployment") +
ylab("Percentage")
