I am trying to run a R code from the Python using Subprocess library. I need to run one.R file from the python and have pass one single String value(args = ["INV28338"]). I am new in R and so not able to figure out exact data type conversion code in both R and Python.
Please someone help me, how to pass single string/scalar value from Python to R Function/Model? Later I will give the shape of 'Flask REST API' for this code.
Thank you so much in advance
import subprocess
command = 'Rscript'
path2script = 'classification_model_code.R'
args = ["INV28338"]
cmd = [command, path2script] + args
x = subprocess.check_output(cmd, universal_newlines=True)
print('The Output is:', x)
myArgs <- commandArgs(trailingOnly = TRUE)
nums = as.numeric(myArgs)
invoice_in_scope<-nums
#Followed by more code
my script, test2.R
myArgs <- commandArgs(trailingOnly = TRUE)
nums = as.character(myArgs)
print(nums)
you need to have args
as part of the list, so append it to cmd
and it works ok:
import subprocess
command = 'Rscript'
path2script = './test2.R'
args = "INV28338"
cmd = [command, path2script]
cmd.append(args)
x = subprocess.check_output(cmd, universal_newlines=True)
print('The Output is:', x)
