Hello,

I'd like to estimate propensity scores for multiple treatments and try to use the mnps command in Stata (https://www.rand.org/statistics/twang/downloads.html). I have followed the codes suggested by online tutorial. However, I am facing the following error: Fatal error: you must specify '--save', '--no-save' or '--vanilla'. I would be grateful if you could advise something to address this issue.

Code:
.

global ado "/Users/smp462/Desktop/State/twang/ado files"
adopath + "$ado"

mnps st $demo $race $income $edu $married $dual $living $area $health1 $health2 i.year, ///
   ntrees(3000) intdepth(3) shrinkage(0.01) ///
   stopmethod(es.mean ks.mean) estimand(ATE) ///
   rcmd(/usr/local/bin/r/) ///
   objpath(/Users/smp462/Desktop/Stata/twang/output) ///
   plotname(/Users/smp462/Desktop/Stata/twang/mnps_example_plot.pdf)

Running R script, please wait...

ARGUMENT '/Users/smp462/Desktop/Stata/twang/output/mnps.R' __ignored__

Fatal error: you must specify '--save', '--no-save' or '--vanilla'
Error: R did not complete successfully.
file /Users/smp462/Desktop/Stata/twang/output/mnps.Rout not found
r(601);
FYI, the following is the codes suggested by online tutorial (https://www.rand.org/statistics/twan...-tutorial.html).
Code:
mnps treat illact crimjust subprob subdep white, ///
ntrees(3000) intdepth(3) shrinkage(0.01) ///
stopmethod(es.mean ks.mean) estimand(ATE) ///
rcmd(C:\Program Files\R\R-3.3.1\bin\Rscript.exe) ///

plotname(C:\users\username\twang\output\mnps_example_plot.pdf)
save C:\Users\username\twang\output\aod_ate_wgts, replace
Thank you in advance!
