本文介绍了ggplot2中的交互图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在尝试使用 ggplot2 进行交互式绘图。我的代码如下:

  library(ggplot2)
p < - qplot(as.factor(dose),len ,data = ToothGrowth,geom =boxplot,color = supp)+ theme_bw()
p <-p + labs(x =Dose,y =Response)
p <-p + stat_summary(fun.y = mean,geom =point,color =blue)
p <-p + stat_summary(fun.y = mean,geom =line,aes(group = 1) )
p <-p + opts(axis.title.x = theme_text(size = 12,hjust = 0.54,vjust = 0))
p <-p + opts(axis.title.y = )
print(p)

我如何绘制剂量补充水平组合的方式,而不是只有剂量水平的手段,我在这里?提前感谢您的帮助。



解决方案

您可以预先计算自己的数据框中的值:

(牙齿增长,(dose,supp),总结,val =平均(len))

ggplot(ToothGrowth,aes( x =因子(剂量),y = len,color = supp))+
geom_boxplot()+
geom_point(data = toothInt,aes(y = val))+
geom_line = toothInt,aes(y = val,group = supp))+
theme_bw()


请注意,使用 ggplot 而不是 qplot 使图表构造更加清晰,适用于更复杂的图表(如IMHO)。

I'm trying to make interaction plot with ggplot2. My code is below:

library(ggplot2)
p <- qplot(as.factor(dose), len, data=ToothGrowth, geom = "boxplot", color = supp) + theme_bw()
p <- p + labs(x="Dose", y="Response")
p <- p + stat_summary(fun.y = mean, geom = "point", color = "blue")
p <- p + stat_summary(fun.y = mean, geom = "line", aes(group = 1))
p <- p  + opts(axis.title.x = theme_text(size = 12, hjust = 0.54, vjust = 0))
p <- p  + opts(axis.title.y = theme_text(size = 12, angle = 90,  vjust = 0.25))
print(p)

How can I plot dose-supp level combination means rather than only dose level means which I'm getting here? Thanks in advance for your help.

解决方案

You can precalculate the values in their own data frame:

toothInt <- ddply(ToothGrowth,.(dose,supp),summarise, val = mean(len))

ggplot(ToothGrowth, aes(x = factor(dose), y = len, colour = supp)) + 
    geom_boxplot() + 
    geom_point(data = toothInt, aes(y = val)) +
    geom_line(data = toothInt, aes(y = val, group = supp)) + 
    theme_bw()

Note that using ggplot rather than qplot makes the graph construction a lot clearer for more complex plots like these (IMHO).
