问题
Having problems to get an R-script to plot "inline" in Ipython (Jupyter) using the irkernel. The script runs fine but the graphics are displayed in a 'Quartz Windows' instead of inline. How can I change this behavior? Have tried running the same script in Rstudio and get similar but inconsistent behavior. In this case some graphs are displayed within Rstudio while others are displayed in 'Quartz'.
Environment is Jupyter latest, irkernel on OSX Yosemite
