distr包 - 如何在一个窗口中绘制两个图? [英] distr package-how to draw two plots in one window?
问题描述
我使用 distr
来形成以下分配:库(distr)
G1 < - Gammad(shape = 1.64,scale = 0.766)
G2 < - Gammad(shape = 0.243,scale = 4.414)
现在为了比较我需要在一个窗口中绘制它们的这两个分布,但我不知道如何。我尝试了 ggplot
,但显然它不适用于gamma函数。
使用ggplot
您可以使用 stat_function
例如
#定义您感兴趣的x值范围的数据
DF< -data.frame( x = c(1,8))
ggplot(DF,aes(x = x))+
stat_function(fun = d(G1),aes(color ='G1'))+
stat_function(fun = d(G2),aes(color ='G2'))+
scale_colour_manual('Distribution',
values = setNames(c('red','blue'), c('G1','G2')))
使用base
distr :: plot
的帮助文件显示了如何组合图表。
您需要设置 mfrow
(或 mfcol
),然后设置 mfColRow = FALSE
无线
例如:
par(mfrow = (G2,mfColRow = F)
$($)
plot b
$ b
I am using distr
to form the following distributions:
library(distr)
G1 <- Gammad(shape=1.64, scale=0.766)
G2<- Gammad(shape=0.243, scale=4.414)
now in order to compare these two distributions I need to plot them in one window, but I don't know how. I tried ggplot
but apparently it does not work with gamma function.
Using ggplot
you can use stat_function
eg
# data that defines the range of x values you are interested in
DF <-data.frame(x = c(1,8))
ggplot(DF, aes(x=x)) +
stat_function(fun = d(G1), aes(colour = 'G1')) +
stat_function(fun = d(G2), aes(colour = 'G2')) +
scale_colour_manual('Distribution',
values = setNames(c('red', 'blue'), c('G1', 'G2')))
Using base
The help file for distr::plot
shows how to combine plots.
You need to set mfrow
(or mfcol
) yourself, then set mfColRow =FALSE
within the plot call.
eg:
par(mfrow=c(2,3))
plot(G1, mfColRow=F)
plot(G2, mfColRow=F)
