Ok, when I use https://sagecell.sagemath.org/ it works perfectly fine.

Thank you for your answer. I am using Sage via CoCalc. When I open a new Sage worksheet and type:

r

x = r([10.4,5.6,3.1,6.4,21.7]); x

I get:

<function r="" at="" 0x7fd8f6b5f5f0="">

Error in lines 1-1 Traceback (most recent call last): File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_server.py", line 1013, in execute exec compile(block+'\n', '', 'single') in namespace, locals File "", line 1, in <module> File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_salvus.py", line 2168, in r return r.jupyter_kernel(code,**kwargs) File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_jupyter.py", line 179, in run_code msg_id = kc.execute(code) File "/ext/sage/sage-8.0/local/lib/python2.7/site-packages/jupyter_client/client.py", line 244, in execute raise ...

I am a beginner to Sage but I used to work with R. I know that I can create a R syntax cell by putting %r at the beginning of the cell. But there are a lot of examples which use the r.xyz syntax (for example: x = r([10.4,5.6,3.1,6.4,21.7]); x). But none of these examples work for me, what am I doing wrong?
