Hello,
You're using OpenTURNS from anaconda which unfortunately isn't built for
graphing using the old R interface (to be deprecated), but:
- You can use the matplotlib module to plot even nicer graphs:
from openturns.viewer import View
View( pdfLoiE ).save(' distributionE.pdf' )
View( pdfLoiE ).show()
- Or install R, and tell OpenTURNS where to find the interpreter your script:
conda install -c r r-base
ResourceMap.Set('R-executable', ' /home/francois/anaconda2/ bin/R')
