[英]R - geom_smooth, add se for only one line
Is there a way, in geom_smooth()
(from libray ggplot2 ), to have the confidence interval (parameters se = T
) for a line but not for the other ? 在
geom_smooth()
(来自libray ggplot2 )中,是否有办法让一条线具有置信区间(参数se = T
),而另一条线则没有?
mpg %>%
filter(class %in% c('compact', 'midsize')) %>%
ggplot(aes(x = displ, y = as.numeric(hwy), color = class)) +
geom_smooth(se = T)
In the graph below, I would like to keep the confidence interval for the blue line, but to remove the one of the red line. 在下图中,我想保留蓝线的置信区间,但要删除红线之一。 As
se
parameter is not in the aes()
function, I don't manage to pass different values in it. 由于
se
参数不在aes()
函数中,因此我无法在其中传递不同的值。 Moreover, there is no function like scale_fill_manual()
, to specify different values. 而且,没有像
scale_fill_manual()
这样的函数来指定不同的值。
This should work: 这应该工作:
mpg %>%
filter(class %in% c('compact', 'midsize')) %>%
ggplot(aes(x = displ, y = as.numeric(hwy), color = class)) +
geom_smooth(data = . %>% filter(class == "compact"), method = "loess", se = F) +
geom_smooth(data = . %>% filter(class == "midsize"), method = "loess", se = T)
