Hi openturns users,
I am facing a problem when ploting stuff in openturns. In particular when I run
this minimal example taken from example 1 : deviation of a cantilever beam
from openturns import *
distributionE = Beta(0.93, 3.2, 2.8e7, 4.8e7)
pdfLoiE = distributionE.drawPDF()
# Change the legend
draw_E = pdfLoiE.getDrawable(0)
draw_E.setLegend("Beta(0.93, 3.2, 2.8e7, 4.8e7)")
pdfLoiE.setDrawable(draw_E,0)
# Change the title
pdfLoiE.setTitle("PDF of E")
pdfLoiE.draw("distributionE_pdf", 640, 480)
I get
RuntimeError Traceback (most recent call last)
<ipython-input-10-d23f041bd8eb> in <module>()
----> 1 pdfLoiE.draw("distributionE_pdf", 640, 480)
/home/francois/anaconda2/lib/python2.7/site-packages/openturns/graph.pyc in
draw(self, *args)
4295 Number of pixels fixing the height of the Graph, default value=480.

RuntimeError: InternalException : GraphImplementation: error trying to execute
R command=R_EXECUTABLE-NOTFOUND --no-save --silent < "/tmp/tmp_graph.R.U7TQC7"
> /dev/null 2>&1
Do you have any ideas ?
Thanks a lot
Francois
