Script test seems to not have correct working directory

Question

I am trying to see if I can get code examples to run in my user account, rather than the testuser account. To that end, I did the following:

• I have created a folder example-fraud-score under my DeployR user account (not the testuser as laid out in the tutorial, found here: https://msdn.microsoft.com/en-us/microsoft-r/deployr-data-scientist-getting-started )
• uploaded the contents of analytics/ from the tutorial to the example-fraud-score directory on the DeployR server.
• Attempted to run the file ccFraudScore.R , contents here: https://github.com/Microsoft/js-example-fraud-score-basics/blob/master/analytics/ccFraudScore.R using the 'Test' tab on the right after clicking on the filename in DeployR.

When I do, I get the error:

Connecting to 172.31.232.190:8000
3:53:26 PM Stream Connect matthew.pettis connection established, waiting for an event...
> require(deployrUtils)

> deployrInput("{\"name\": \"credit\", \"render\":\"integer\", \"default\": 8, \"min\" : 0, \"max\": 75 }")
> if (!exists("fraudModel")) {
+ load("fraudModel.rData")
Console Error cannot open the connection
API Error cannot open the connection

I tried following the post here to troubleshoot, but I could not find where my directory was: deployR cannot open the connection

When I used the script to look for the working directory (and list contents), I see:

> require(deployrUtils)
> getwd()
[1] "C:/PROGRA~1/MICROS~2/DEPLOY~1.0/rserve/workdir/conn2209460"
> list.files(getwd())
[1] "DeployREngineSource.r" "unnamedplot001.png"

This seems like the wrong directory to be using. When I try to hunt around for my directory for my user, I can't seem to find it. My DeployR version is 8.0.0.

Help is appreciated.

Thanks, Matt

Answer 1

Is that the remote directory (the second box)? If so, why don't you call setwd() ?
