作为脚本运行时，ggplot无输出 [英] No output from ggplot when running as a script

问题描述

很抱歉打扰您一个肯定是非常简单的错误，但是我仍然无法自己解决这个问题:

Sorry to bother you with what is for sure a very simple mistake, but I still cannot figure it out by myself:

library(ggplot2)

X = rep(c(1:6),3)
Y = rep(c(1:6),3)
group = rep(c(1:3), each = 6)

data = data.frame(X = X, Y = Y, group = group)

ggplot(data, aes(x = X, y = Y, group = group)) + geom_point() 

作为脚本运行时，我没有得到任何输出-没有创建任何图形.我在这里做什么错了?

I do not get any output from this when I run as a script -- no figure is created. What am I doing wrong here?

推荐答案

如果从其他函数或Shiny中调用该图，请尝试打印该图:

Try print the plot if you are calling it from another function or in Shiny:

myplot <- ggplot(data, aes(x = X, y = Y, group = group)) + geom_point() 

print(myplot)
