如果要画出来的话,interaction.plot()可以作出交互效应图,
考查因素之间交互作用是否存在, 比如
>op<-par(mfrow=c(1, 2))
>plot(Time~Toxicant+Cure, data=rats)
>with(rats, interaction.plot(Toxicant, Cure, Time, trace.label="Cure"))
>with(rats,interaction.plot(Cure, Toxicant, Time, trace.label="Toxicant"))
说明是:
Use box plots and line plots to visualize group differences. There are also two functions specifically designed for visualizing mean differences in ANOVA ayouts. interaction.plot( ) in the base stats package produces plots for two-way interactions.
你先写一个函数,然后在R的界面加载新建一个脚本:
fun<-function(x){
if(x>=0 &x<=3) y=3*x+2
else y=2*x-0.5*x^2
y
}
保存为fun.R
然后在R界面里
>source("fun.R")
>x<-seq(0,6,0.01) 每隔0.01取一个点
>y<-fun(x)
>plot(x,y)
答:1,打开origin,在输入框中输入自己采集到的数据。其中LongName填的是名称,UnitS填的是单位。2,点击“plot”,选择图表的类型,或者直接在下方选择图表类型。3,然后选择每个名字相对应的坐标轴。4,然后就会生成相对应的图片……
