Availability of R in Sage 8.x Windows version?
dhou...@goshen.edu
I installed Sage 8.1 with the Windows binary:
'SageMath version 8.1, Release Date: 2017-12-07'
In a new Sage notebook, I executed the following commands:
data = [2, 3, 7, 8, 10, 11]
print median(data)
print r.quantile(data,.5)
r.boxplot(data)
This works in SageMathCell (lines 2 and 3 returning 15/2 and 7.5 and line 4
returning an object that includes a displayed boxplot); however, in Sage
8.1 Notebook on my Windows 7 machine (Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz 2.30 GHz, 64-bit Operating System), line 4 returns
[1] 2
and the command
r.png()
returns the following Python traceback:
--------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) <ipython-input-3-5d43610b342f> in <module>() ----> 1 r.png() /opt/sagemath-8.1/local/lib/python2.7/site-packages/sage/interfaces/r.py in png(self, *args, **kwds) 445 t = r.eval('capabilities("aqua")') 446 if "TRUE" not in s+t: --> 447 raise RuntimeError("R was not compiled with PNG support") 448 449 from sage.server.support import EMBEDDED_MODE RuntimeError: R was not compiled with PNG support
When I google searched on various words, I kept coming upon information from about 6-8 years ago dealing with different headers in the compile phase and the presence or absence of an X11 server. Do I really need to install an X11 server, download the SageMath source, make a variety of compiler choices, and compile myself?
I also tried the above on my office Windows computer with Sage 8.2 and obtained the same result. When I tried installing Sage 8.2 on my home computer, Windows responds that SageMath-8.2.exe is not a valid Win32 application. When I tried the above code in CoCalc, it appears that R is not a recognized object:
Error in lines 3-3 Traceback (most recent call last): File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_server.py", line 1043, in execute exec compile(block+'\n', '', 'single', flags=compile_flags) in namespace, locals File "", line 1, in <module> AttributeError: 'function' object has no attribute 'quantile'
