Calling/Running python module in R
I installed rPython on my Windows 10 computer. The library seems to work fine. Thanks! As I am new to Python I could use some help running a python module in R. I tried various search strings on Google, but I could not find the answer. Hopefully, you could help me.
The problem is as follows. I installed the kpss module by jejansse. In python, the stem function works well, called by [kpss.stem(t) for t in "Alle eendjes zwemmen in het water".split()]).
Next, I managed to install rPython and loaded the required module using the function python.load("C:/Python27/Lib/kpss.py") . However, I do not know how to call the kpss.stem function. I played around with the assign and call functions, but these functions do not seem to work.
Your help is very much appreciated.
Reading the rPython documentations carefully and with some trail and error, I found the solution myself.
In R:
python.exec( "import kpss" )
t<-c("eendjes")
python.call( "kpss.stem", t)
[1] "eend"
What does not work yet is the "for loop", When a string consisting of several words is used, the for loop is ignored and only the last word is stemmed.
Best, Peter
python.exec('import pandas as pd') python.exec('print(pd.version)')
results nothing. I use rPython_0.0-6 RJSONIO_1.3-0 and Python 3.6.4.
Your help is very much appreciated.
