【问题描述】:
我试图为不重要的系数 (p>0.05) 和重要的系数显示不同的颜色。另外,如果有人有办法显示图例或表示颜色,那也不错..
有什么想法吗?
示例代码:
library(nycflights13)
library(dplyr)
library(dotwhisker)
library(MASS)
flights <- nycflights13::flights
flights<- sample_n (flights, 500)
m1<- glm(formula = arr_delay ~ dep_time + origin+ air_time+ distance , data = flights)
#m1<- glm(formula = arr_delay ~ . , data = flights)
m1<- stepAIC(m1)
p<- dotwhisker::dwplot(m1)
z<- p +
geom_vline(xintercept=0, linetype="dashed")+
geom_segment(aes(x=conf.low,y=term,xend=conf.high,
yend=term,col=p.value<0.05)) +
geom_point(aes(x=estimate,y=term,col=p.value<0.05)) +
xlab("standardized coefficient") +
ylab("coefficient") +
ggtitle("coefficients in the model and significance")
print(z)
