使用ggplot的geom_rug中的不同数据比我在其余的绘图中使用的数据要多 [英] Using different data in ggplot's geom_rug than I use in the rest of the plot
问题描述
我无法使用geom_rug将某些数据绘制到现有的绘图中。下面是一个示例图,我将一些访问日与某个度量的大小进行比较。
test< - data.frame (
visit = rep(c(0,1.5,3.5,6.5,12),5),
mag = rnorm(n = 25)
)
ggplot(test,aes(x = visit,y = mag))+ geom_point()
以下情节。
我还有一些其他数据,我想只在x轴上添加额外的标记。
vac < - data.frame(
visit = c(2,4,6,8)
)
由于我不明白的原因,当我运行时,下面的代码。
ggplot(test,aes(x = visit,y = mag))+ geom_point()+
geom_rug(data = vac,aes(x = visit))
我想我已经搞砸了在某种程度上语法,但我似乎无法弄清楚我在这里做错了什么。任何建议?
您应该指定 inherit.aes = FALSE
in geom_rug()
行,否则它从主 ggplot()继承
y = mag
call。
ggplot(test,aes(x = visit,y = mag))+
geom_point()+
geom_rug(data = vac,aes(x = visit),inherit.aes = F)
I am having trouble getting geom_rug to plot some data into an existing plot. Here's an example plot, where I am comparing some visit day to the magnitude of some measurement.
test <- data.frame(
visit = rep(c(0, 1.5, 3.5, 6.5, 12), 5),
mag = rnorm(n = 25)
)
ggplot(test, aes(x = visit, y = mag)) + geom_point()
Which generates the following plot.
I also have some other data, that I'd like to add just as extra marks on the x axis.
vac <- data.frame(
visit = c(2, 4, 6, 8)
)
For reasons I don't understand, I get no plot at all when I run the following code.
ggplot(test, aes(x = visit, y = mag)) + geom_point() +
geom_rug(data=vac, aes(x = visit))
I presume I have messed up on syntax somehow, but I can't seem to figure out what I am doing wrong here. Any suggestions?
You should specify inherit.aes = FALSE
in the geom_rug()
line, otherwise it inherits y = mag
from the main ggplot()
call.
ggplot(test, aes(x = visit, y = mag)) +
geom_point() +
geom_rug(data=vac, aes(x = visit), inherit.aes = F)
