为什么在使用rpy2的Mac中无法正确显示情节？

Question

I'm trying to make R plot in Python via rpy2 in Mac, but the plot is not shown up completely or python crashes after I close the window.

If I run the codes below without r.quartz() , there will be no graph at all but there is a pdf file named 'Rplot' generated in my folder which cannot be opened.

If I run the codes below with r.quartz() , plot will show up but python will quit unexpectedly after I close the graph window. I tried the codes in Windows and they work well.

import rpy2.robjects as robjects

r = robjects.r

x = robjects.IntVector(range(10))

y = r.rnorm(10)

r.quartz()

r.layout(r.matrix(robjects.IntVector([1,2,3,2]), nrow=2, ncol=2))

r.plot(r.runif(10), y, xlab="runif", ylab="foo/bar", col="red")

Depending on your local R settings, by default R might create a PDF graphical devices (for more information about graphical devices in the context of rpy2, see the doc: https://rpy2.github.io/doc/v3.1.x/html/graphics.html#graphical-devices ).

Regarding Python terminating, are you using Python interactively or you are running a script (eg, python myscript.py ) ? If the latter, it would be normal for Python to exit after the script reached the end of its execution.
