I'm using the package: IBrokers. It works well for me when I request historical data. Also the call to reqAccountUpdates() works well.
I am having problems with this script:
# myscript.r
.libPaths("rpackages")
library(IBrokers)
tws2 = twsConnect(2)
print('Attempting BUY')
mytkr = twsFuture("ES","GLOBEX","201412")
myorderid = sample(1001:3001, 1)
IBrokers:::.placeOrder(tws2, mytkr, twsOrder(myorderid, "BUY", "1", "MKT"))
twsDisconnect(tws2)
Sometimes the above script works okay. Usually though it fails. When it fails, it seems to connect okay.
Then I see this in my TWS console:

Can you offer any ideas on how you would wrestle with this issue?
One other piece of info:
I think the call to reqIds() may be necessary. Sometimes reqIds() would return an id not high enough. Then, I'd use it and placeOrder() would fail. So, I call reqIds() but then use Sys.time() to give me an id which is larger than the last ID I used.
Another problem may have been some code-text I copied out of a PowerPoint. Some of the code-characters may have been corrupt.
The main problem was orderid.
I need to be careful how I generate orderid.
Also I may have moused in bad characters from a powerpoint preso which had an example.
I posted some code which works in a comment in this thread.
